When her husband Harry walks out after just six months, a girls' weekend away with two friends seems like just what Sam needs.
But they aren't even halfway to their destination when things start to go wrong: car trouble that just happens to leave them stranded in the town where Harry lives.
And that's only the beginning.
Because there are three things Sam doesn't yet know:
One of her friends is lying about what happened.
One is lying about who she is.
And one of them will never make it home . . .
