Driving home one night, Gabe sees the face of a little girl he knows in the rear window of the car in front. She mouths one word - 'Daddy'. He never sees his five-year-old daughter, Izzy, again. The police believe she's dead. But three years later, Gabe still drives the roads, searching for the car that took Izzy, never giving up hope . . . Fran and her daughter, Alice, aren't searching - but running. Always one step ahead of the people who want to hurt them. Because Fran knows the truth about Gabe's daughter - and she knows what those chasing her and Alice will do if they ever catch them . . .
