Sarah (Tatiana Maslany) is about to catch a train when she sees someone jump in front of it. Her life changes when she notices that the jumper looks exactly like her. Sarah steals the woman's purse and assumes her life, which leads to a season's worth of complications. This BBC America series created by "Cube" writer Graeme Manson delivers the breathless plot convolutions required for a highly addictive TV series, but the characters come off a bit shallow.
