Ringer (Season 1)

Ringer (2011) is an American mystery drama series you can watch online on iFILM. Sarah Michelle Gellar plays twin sisters — Bridget, a woman on the run from the mob, and Siobhan, her wealthy Manhattan counterpart — across one season of 22 episodes.

Bridget has just agreed to testify against a dangerous crime figure and immediately becomes a target. She tracks down her estranged twin sister in New York. Then Siobhan vanishes. Bridget takes over her identity, expecting safety — but Siobhan's picture-perfect life turns out to carry its own debts, enemies, and secrets. Bridget is now running from two separate sets of people who want her dead.

The series aired on The CW and marked Gellar's first major TV role since Buffy the Vampire Slayer ended. The dual-identity hook keeps the plot churning, and Gellar makes the two women distinct enough to follow. The show rewards viewers who enjoy procedural mysteries layered with long-running conspiracies — each episode adds another piece to a puzzle that keeps shifting.
