Lt. Michael Kenmore awakens in Atlantis's infirmary with no memory of how he got there — or who he is. Dr. Weir, Col. Sheppard and Dr. Beckett explain that he's a member of the expedition's military contingent who was captured by the Wraith during a dangerous mission. Although Sheppard's team rescued him, he was badly injured and has been unconscious for days.

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.
