Plot
The premiere episode opens where the season two finale, Allies, left off. With the help of the Daedalus and the Orion, as well as assistance from Michael, Col. Sheppard manages to rescue Ronon and McKay from the Wraith ships and then destroy one and capture the other. After using the iratus bug retrovirus on the survivors of the captured hive, as well as Michael, the expedition deposits them on a habitable planet and continues regularly injecting them to keep them human. However, they soon realize what the humans are doing, managing to revert back to Wraith form and contact a hive to pick them up. In this event, Atlantis' hive ship is destroyed. Most of the Wraith are killed, but Michael survives. Atlantis 1 goes on to have numerous adventures throughout this season, meeting a man with an addictive personality and falling victim to a Wraith hallucinatory device. Ronon is captured by the Wraith and made to become a runner again on his homeworld, and Rodney McKay's genius sister comes to Atlantis to work on a project that ends up depleting the city's ZPM. Atlantis meets a new enemy who seek to destroy all humans; the Daedalus finds an Ancient warship with live Ancients on board. When the ancients return to Atlantis, the mysterious new enemy takes over the city, and Col. Sheppard's team has to fight an uphill battle to regain control. Atlantis is almost destroyed by a solar flare but is saved by telepathic whales. The team again runs into Lucius Lavin and Acastus Kolya, as well as finding a planet controlled by an Ancient video game. Rodney is given superhuman semi-Ascended powers, and the team finds a world where people have hidden from the Wraith inside one of the data storage devices found on Wraith darts. One character leaves Atlantis when a bomb goes off in the city, and the team finds an Ancient geothermal platform to supplement their ZPM. Michael returns when Atlantis 1 goes looking for missing villagers, and the season finale features an attack on Atlantis that leaves the city crippled, lost in space, and with only 24 hours of oxygen.
