Sarah Michelle Gellar returns to TV this fall in the CW drama Ringer. The actress, 34, plays twin sisters Bridget and Siobhan. When Siobhan disappears on a boating excursion, Bridget assumes her sister is dead. The troubled twin then takes on her sister's seemingly glamorous identity.
"I'm the only one that knows that she's dead!" Bridget exclaims. She soon discovers that Siobhan is a wanted woman, and failingly tries to convince her sister's enemies that they have the wrong girl.
Watch a preview for Ringer above, and tune in for the premiere Sept. 13 at 9 p.m. (EST) on the CW.
