Meet Lou Farnt: a 30-something, self-help addict who wants nothing more than to escape her overly controlling mother and the dead-end seaside town where she grew up.

So, when strange and strikingly confident new life coach Val suddenly arrives on the scene and invites her on a road trip of alternative therapies, Lou finds the perfect opportunity to leave, and the perfect person to become.

Unfortunately for Lou, Val just happens to be a serial killer.
