Two strangers, Cait and Rebecca, are driving across America.
Rebecca is trying to escape something. Cait doesn't know what Rebecca has left behind her - she doesn't ask any questions - her job is solely to transport women to safety. But the secrets Rebecca holds could put them both in danger.
Cait too has a past of her own - there's a reason she chooses to spend time on the road, looking out for others.
Because she knows what it's like to be followed. As the two women travel across America, it quickly becomes clear someone is right behind them, watching their every move. The question is: who, and why?
