When Atlantis's deep-space sensors detect the Aurora, an ancient Atlantian warship, at the edge of the galaxy, Sheppard's team wastes no time hitching a ride to it aboard the Daedalus. Upon their arrival, they encounter a Wraith scout ship. They destroy the scout before it can cause trouble — or so they hope.

Colonel Sheppard and his team find themselves prisoners of the Wraith following Ford's attack on a hive ship. Dr. McKay goes to great lengths to help them.
