Reluctant Witness (2015)

Erin was married to a gangster, but after finally deciding to leave him, she asked the FBI for protection. The FBI responded by placing her in the witness protection program, giving her a new identity. Having moved to Northern California, she falls for her new best friend's brother, a vineyard owner. Ten years on, her best friend gets involved with a man, and Erin, now known as Becky, becomes increasingly convinced that he is her former spouse, who was thought to have died.
