When Regina is accused of murdering a beloved fairy-tale character, Emma thinks she is innocent; Prince Charming and Snow White plan the evil queen's execution.

With the Wraith armada bearing down on the city the Atlantis team prepares to evacuate. Setting the city’s self-destruct sequence they hope to make it impossible for the Wraith to gain access to Earth. Things begin to look up when reinforcements from Earth are brought in and it is announced that the battleship Daedalus will arrive in four days. However when the warheads are easily destroyed by the Wraith and the first wave of Wraith attackers strafe the city with weapons fire it becomes increasingly clear that the added reinforcements are not going to be enough. With time running out the Atlantis team must turn to the least likely source of aid – the duplicitous Genii! But with the Wraith overrunning the city even the Genii’s help may not be enough.

With the Wraith armada closing in on Atlantis Dr. McKay (David Hewlett) and a small team attempt to repair an ancient weapons satellite in the hopes of leveling the odds in the coming battle. Meanwhile tension builds between Teyla and some of the other members of the Atlantis team over her connection to the Wraith. Major Sheppard (Joe Flanigan) steps in to defend her but even he begins to harbour doubts when a team member is left unconscious after an attack by an unknown assailant.

Terrifying nightmares about the Wraith cause Teyla (Rachel Luttrell) to lash out at her colleagues and prompt her to seek professional advice. With psychological guidance she discovers that she can sense the Wraith. In their search to learn more Teyla and the Atlantis team discover important information that may hold the key to understanding their enemy including the disturbing possibility that Teyla's connection to the Wraith could be the result of genetic experimentation.

While assessing the structural damage to the city caused by a massive storm two of Dr. McKay's (David Hewlett) team of scientists experience horrifying visions. Minutes later they drop dead. Retracing the steps of the dead scientists McKay and his team find an Ancient lab its contents in disarray. Afraid of a viral outbreak Dr. Weir (Torri Higginson) places the city under a self-regulated quarantine. Even with the city under lockdown under the threat of a possible viral outbreak more and more people begin suffering from the same terrifying visions. If McKay cannot find a cure the entire city will be doomed.
