2x11 The Hive, Part 2

Captured by the Wraith, Sheppard (Joe Flanigan), Teyla (Rachel Luttrell),
Ronon (Jason Momoa) and Ford (Rainbow Sun Francks) are being held hostage
aboard a hive ship. As the team desperately searches for some means of escape, they are shocked to discover a coalition of Wraith followers on board the ship.

McKay, who is still stranded on Ford's planet, soon realizes that the team has been captured. In order to escape the planet, he comes up with an unconventional plan: he injects himself with a massive amount of the dangerous Wraith enzyme. The drug provides him with brute strength, and after knocking the guards that surround him unconscious, he is able to dial the gate and leave the planet. When he arrives on Atlantis completely incoherent, Dr. Weir (Torri Higginson) and Dr. Beckett (Paul McGillion) put him under immediate medical supervision.

Once recovered, McKay is able to calculate the location of the ship upon which the team is stranded. As tensions rise on the hive ship between the Wraith and the Atlantis team, he and Caldwell (Mitch Pileggi) must devise a plan to bring the rest of their team to safety.
