President Roslin's fears that Commander Adama is a Cylon are stoked when she learns he's making secret wireless calls to other ships. Then, to make things worse, a single Cylon raider appears near the Galactica and begins acting strangely after being damaged in battle.
When Adama returns to the ship with Tigh's wife, Ellen, an earthy temptress and irrepressible flirt who claims to have been in a coma since their civilization was destroyed, Roslin's suspicions increase. She orders Baltar to screen both Ellen and Adama with his newly completed Cylon-detector.
Meanwhile, Col. Tigh and the rest of the crew watch warily and gather data as the wounded Cylon raider jumps in and out of space.
On Caprica, the Cylon overseers fear that the Cylon Sharon is developing a strange feeling toward Helo - love.
