30-something, self-help addict, Lou Farnt wants nothing more than to escape her overly controlling mother and the dead-end seaside town where she grew up. When strange and strikingly confident new life coach Val invites Lou on a road trip of alternative therapies, culminating with a visit to American self-help idol Chuck Knoah's British country home, Lou finds the perfect opportunity to leave, and the perfect person to become.

Unfortunately for Lou, Val's a serial killer.
