Addison is about to get married but is not looking forward to the big day. She doesn't know who she really is. A few years ago, a kind driver found her bleeding next to a New Jersey highway and rescued her. While her physical wounds healed, Addison’s memory never returned. She doesn’t know her real name. Or how she ended up injured on the side of a road. Or why she can’t shake the notion that she may have done something very, very bad. In a posh home in the Boston suburbs, Julian tries to figure out what happened to his loving, caring wife, Cassandra, who disappeared without a trace two years ago. She never would have left him and their seven-year-old daughter Valentina of her own free will. Or would she?
