      With the arrival of the Apollo to Atlantis comes intel that the Replicators appear to be building a large armada to directly attack earth. Planning to strike first, Col. Ellis with the aid of the Atlantis team launches a surgical strike nuking the entire armada. Believing that all imminent danger has been avoided the team is shocked when a satellite housing a stargate takes up geosynchronous orbit above Atlantis. Unable to destroy the Stargate, it opens transmitting a powerful energy beam impacting Atlantis' shields. Being powered from the point of origin, neither the beam nor the satellite's shields show any vulnerability to the Apollo or Atlantis. Without any way of avoiding the beam as it quickly drains the ZPM powering the shields, Rodney McKay opts to sink the city as the ancients did millennia ago using the water to dissipate the beams strength. But when the sinking of the city doesn't have the desired effects, it appears it's only a matter of time before the shields fail. With the stargate active in such close proximity, it renders the city's gate inactive. Their only hope is to use what energy the ZPM has left along with strategic cover by an asteroid to hopefully fly the city into hyperspace before the shields collapse. But when the asteroid fails to hold, allowing the beam to cut through to the city, it seems unlikely Atlantis will make it off the surface in one piece.

Once there, it appears the Taranans have just abandoned their village until Rodney McKay (David Hewlett) detects life signs well beneath the surface in the remnants of the previous village's underground industrial complex. Searching the dark winding corridors of the abandoned tunnels the team comes upon some sort of cocoon as well as a lab that appears to have been used for Wraith experiments. Discovering the bodies of several Taranans who appeared to have been fed on by the Iratus bug, the team has little time to piece the puzzle together before they themselves are attacked by a large insect-like monster. Their weapons are useless against the creature’s exoskeleton. Ronon is barely able to fend it off by cutting off one of its arms.

Weir (Torri Higginson), believing it's just the pressure affecting Teyla, has the team press on to explore the station. Without warning, Teyla suddenly attacks Ronon (Jason Momoa) and sets up a series of force fields to block the team from the jumper. But when Col. Sheppard (Joe Flanigan) corners her she has no memory of doing anything wrong. Using Teyla successfully as a puppet a Wraith Queen, now aboard the station, attacks two scientists to lure Sheppard to the jumper in hopes of using him to fly her to the surface. Unable to overcome the power of the Queen, Sheppard is helpless and saved only by Ronon mistakenly blasting the jumper windows sending a wall of ocean water onto Sheppard and the Queen. With the Wraith Queen now restrained and sedated Teyla uses her gift to learn that the Queen was part of the first wave of attacks on Atlantis. Her cruiser was shot down sending it plummeting to the ocean depths. Surviving only by feeding on her crew, she woke between centuries in the hope of a rescue that never came.

      A Wraith hive ship arrives in orbit above Atlantis. In the cloaked city below, everyone is stunned when Michael radios down with an unnerving request: He wants to negotiate an alliance. Frustrated in their quest to locate Earth, the Wraith are now running short of their food — humans — and have begun fighting among themselves. For this reason, Michael seeks a weaponized version of Dr. Beckett's anti-Wraith retrovirus, which briefly gave him a human body. He wants to deploy it against rival hives, turning them human and feasting on the results. His hive will gain food and power, and the Atlantis team can deal a fatal blow to thousands of their enemies. Weir and her senior staff decide that such a payoff is worth the immense risk of trusting the Wraith, and soon the new allies are working side-by-side. With the help of a Wraith scientist, Beckett and Zelenka struggle to weaponize the retrovirus, while McKay coordinates with the hive's crew to practice bypassing a hive ship's defenses. The Wraith, however, make everyone uneasy. Worse, their first attempt to target another ship with the new weapon ends in disaster: Their enemies discover the canisters of the retrovirus too soon and open fire. Michael's hive ship and the Daedalus barely escape intact. The imperious Queen of Michael's hive now threatens to reveal Atlantis's existence to all the Wraith if the humans won't design a reliable delivery system for the weapon. McKay, frustrated, demands that she help by allowing him free access to every last piece of information about Wraith ships. To his astonishment, she agrees, downloading a virtual encyclopedia of technical specs to Atlantis's computers. Zelenka delves into this goldmine of strategic intelligence while McKay — escorted by Ronon — explores the hive itself and discovers a perfect delivery point for the retrovirus in the atmospheric system. With that, they're ready to attempt a second attack: The Daedalus will beam the canister onto another enemy hive. McKay and Ronon will observe from Michael's ship. Sheppard will observe from the Daedalus. But soon after the mission is underway, Zelenka discovers that the electronic Wraith encyclopedia was infected with a virus of its own — and now that virus is loose in Atlantis's computers. It's too late to warn the Daedalus, which drops out of hyperspace to find itself trapped under a ferocious bombardment from two hives — the enemy vessel and Michael's ship. The alliance was nothing but a ruse; the real plans of the Wraith are far more sinister. Far from giving up on finding Earth, they've just tricked the Atlantis team into giving them exactly the information they need to get there.

Lycus also shows the team a massive Ancient warship, much like the Aurora, hidden in a vast warren of tunnels beneath the base. Although the warship is damaged and currently inoperable, Dr. Weir eagerly opens trade negotiations with Lycus as soon as she learns of its existence. As mysterious earthquakes rattle everyone's nerves, McKay overcomes his attraction to Dr. Pero long enough to discover that her people have seriously overtaxed the shield's capabilities. Worse, the shield's energy source is the magma chamber of a supervolcano beneath the base — a volcano that has been destabilized by the excessive energy demands. A catastrophic eruption is now imminent: Half the continent is about to be ripped apart, rendering the entire planet uninhabitable. Everyone must evacuate. As the earthquakes grow stronger, local villagers begin arriving at the base through the relative safety of the Ancient tunnels. Weir and Lycus lead some of them through the stargate to Atlantis, but seconds later, the ground around the 'gate erupts. The stargate sinks forever into a pool of molten rock. From Atlantis, Weir immediately dispatches the Daedalus to Taranis, but it will require multiple trips to evacuate everyone. Sheppard and McKay, knowing that they don't have that much time, start repairing the Ancient warship while Teyla, Ronon, and Dr. Beckett hurry to a nearby settlement, to organize the first group of evacuees. Soon after the Daedalus departs from Taranis, new vents erupt, ash starts falling, and the outside air turns toxic, forcing Beckett, Teyla and Ronon to send the remaining villagers through the tunnels to the warship. Then McKay discovers that a lava flow has sealed the main hangar doors shut. Now, even if he can repair the ship, they'll still have to find a way past this molten barrier. Teyla and Ronon remain in the settlement until they've rounded up the very last of the villagers, only to be trapped when the tunnel that leads to the base collapses. As the duo fights to stay conscious in the deadly air, Sheppard notices that they're missing and descends into the maze of tunnels to find them. Soon he's cut off, too — and even if he somehow makes it back, there's still no guarantee that McKay can even get the warship off the ground.

      Sheppard's team visits the planet Taranis at the invitation of two leading citizens, Dr. Norina Pero and Chancellor Lycus, who want McKay to repair a failing shield generator at an Ancient base they've discovered. Lycus also shows the team a massive Ancient warship, much like the Aurora, hidden in a vast warren of tunnels beneath the base. Although the warship is damaged and currently inoperable, Dr. Weir eagerly opens trade negotiations with Lycus as soon as she learns of its existence. As mysterious earthquakes rattle everyone's nerves, McKay overcomes his attraction to Dr. Pero long enough to discover that her people have seriously overtaxed the shield's capabilities. Worse, the shield's energy source is the magma chamber of a supervolcano beneath the base — a volcano that has been destabilized by the excessive energy demands.

      When a village on a distant planet is ravaged by fire, the team is called in to investigate the damage. In the attack, Major Lorne, a member of an off-world team working there, has seemingly disappeared. Upon further investigation, Teyla (Rachel Luttrell) and Ronon (Jason Momoa) find a wanted list circulating about the village – and on it is Major Lorne's name – along with those of Sheppard (Joe Flanigan) and McKay (David Hewlett). Weir (Torri Higginson) quickly deduces that whoever composed it was seeking people with the Ancient certain gene that provides the ability to operate Ancient technology, including Ancient ships. Compounding matters, the team is contacted by Ladon Radim, a former Genii. Now claiming to have severed ties with Atlantis' old foe, Ladon has an offer: a valuable zero point module in exchange for their help in planning a coup against the Genii. Ladon claims the Genii have been harboring nuclear weapons and are becoming an even greater threat. Skeptical of what they've been told, the team decides to alert Cowen, the Genii leader, of Ladon's plans. Cowen confirms that Ladon is no longer linked with the Genii, and thanks the men for the warning. Satisfied that the Genii pose no immediate threat, Sheppard and McKay plan a raid to simply "appropriate" the ZPM from Ladon. However, when they arrive, their team is taken hostage by Ladon and Cowen, who are, after all, still Genii accomplices. Their plan is to negotiate for Atlantis' Jumper ships which they intend to use to attack the Wraith. Now, Weir must negotiate with the Genii – before it's too late.

Upon opening the pod, they find a woman in stasis. As they speculate about her age, an energy beam emanates from the pod and hits Weir (Torri Higginson), allowing her to harbor the consciousness of the woman inside the pod. Through Weir, the team learns that the woman, Phoebus, was from a race of explorers whose vessel was attacked by the Wraith. She claims that the body of her husband, Thalan, occupies the second of the two pods found by McKay, and her wish is for the team to bring him back to Atlantis so that Sheppard (Joe Flanigan) may harbor the man's consciousness and allow him to communicate one last time with his wife. Unfortunately, once the plan is put into action, the team learns that it was all a ruse: Phoebus and Thalan were enemies, and her real intent was to have the team revive Thalan so she could finally finish him off.

      As the storm approaches, Commander Kolya of the Genii, who has seized Atlantis, is about to shoot Dr. Weir. Suddenly, Dr. Rodney McKay steps in front of the gun and convinces Kolya that he and Weir are the only ones who can fix Grounding Station 3, the last of the four grounding stations that must be disabled so that lightning from the storm can be channeled into the shield generator, to power up the shield and protect Atlantis from being obliterated. Kolya spares their lives, but contacts Maj. John Sheppard over the radio and tells him that Weir is dead. Sheppard vows to kill Kolya. Meanwhile, on the mainland, Lt. Aiden Ford, Teyla and Dr. Carson Beckett are waiting out the storm in a Puddle Jumper. Suddenly, the wind stops and the sky clears. They are in the eye of the storm. Ford commands a reluctant and frightened Beckett to fly the Puddle Jumper straight up the eye, over the storm to Atlantis to help Sheppard. On Atlantis, a female Genii named Sora reports to Kolya that Sheppard has killed three more of their men. Weir and McKay, who are working to bypass the broken switch on the grounding station, overhear the conversation and try to stall the repair to give Sheppard more time. Kolya commands Sora to radio Chief Cowen, leader of the Genii, to send a full company of 60 men through the stargate, dashing Weir and McKay's hopes of rescue. Atlantis is powered by five small Naquadah generators, each responsible for a separate area of the city. Two of the generator rooms are conveniently located near transporter stations. Sheppard disables the generators powering stargate operations and Grounding Station 3, making it impossible for McKay and Weir to finish their task. Sheppard then storms the control room and raises the 'gate shield. Only five of Kolya's 60 men get through. The rest are destroyed by the shield. The storm is less than an hour away. Kolya radios Sheppard with a proposition. If Sheppard doesn't restore power to Grounding Station 3 in the next 10 minutes, Weir really will be killed, followed by McKay 10 minutes later. Sheppard, relieved to hear Weir's voice, has no choice. Joined by Ford, Teyla and Beckett, he restores power to Grounding Station 3. McKay is disables the station. In the control room, Kolya orders McKay to power up the shield. McKay and Weir bluff Kolya into believing that McKay's plan has failed and that Atlantis is lost. He decides to withdraw, but also to take Weir and McKay with him. Sheppard and Ford storm the control room and take out Kolya's remaining men. Kolya uses Weir as a human shield and backs toward the activated stargate. Sheppard takes the shot and hits Kolya, who releases Weir as he falls backward through the 'gate. With the storm due to hit in 2.5 minutes, Teyla and Beckett are unaccounted for. That's because Sora has knocked Beckett unconscious and is fighting Teyla, whom she believes to be responsible for her father's death. Teyla wins but lets Sora live. Sora follows Teyla, who drags Beckett to the control room. Weir gives McKay the order. Lightning strikes Atlantis and floods the corridors. The shield activates just before a huge wave hits the city. Atlantis is saved and Weir orders Sora held as a prisoner.

But the children believe it is their ritual of mandatory suicide at the age of 25 that keeps the enemy at bay, despite the contrary insistence of the Atlantis team. Fearing the “full growns” in their midst will attract the Wraith, the villagers become anxious for their unexpected guests to leave as soon as possible. But to be able to leave, Dr. McKay (David Hewlett) must first disable the electromagnetic field. In doing so, he unwittingly trips a Wraith silent alarm, leaving the tribe open to attack.
