While exploring a new planet Sheppard McKay Teyla and Ronon are ambushed by a group of men armed with Wraith stunners. They awaken to find themselves prisoners in a cave where they discover the mastermind behind the attack: Lt. Aiden Ford. Ford was last seen being captured by a Wraith dart after overdosing on a powerful Wraith enzyme. Now Ford invites his former teammates to enjoy a meal while he tells them how his enzyme-enhanced abilities allowed him to escape. Since that time he has recruited a group of followers all of whom are willingly addicted to the drug. To the team's horror Ford then announces that their meals are laced with the enzyme. Determined to prove that the enzyme is both safe and useful Ford intends Sheppard's team to be his living evidence and the expects Sheppard who remains free of the drug to be his witness.
