Plot Synopsis

Bridget Kelly is on the run from the mob and she takes over the life of her wealthy twin sister Siobhan, but Bridget didn't know there's a bounty on her sister's life as well. As Bridget hides, Agent Machado is tasked with keeping her safe so she can testify against the mob because she witnessed a professional hit. While she tries to live an unfamiliar life, Bridget must convince Siobhan's husband Andrew, Siobhan's best friend Gemma, and Gemma's husband Henry that she's really Siobhan. Instead, she finds that Andrew and Siobhan's seemingly picture-perfect relationship is icy and irreparably damaged. Even Andrew's troubled teenage daughter, Juliet, resents her stepmother, and blames her for the strained relationship she has with her father. But she has the hardest time convincing Henry since he is having an affair with Siobhan, and now he's hurt and confused when that relationship unexpectedly turns very cold. Bridget must now try to unravel the mystery of who is trying to murder Siobhan, and why. She must constantly be on guard to keep her true identity hidden, and soon begins to realize that the secrets run even deeper than she imagined.
