Young newlyweds Paul (Treadaway) and Bea (Rose Leslie) travel to remote lake country for their honeymoon where the promise of private romance awaits them. Shortly after arriving, Paul finds Bea wandering and disoriented in the middle of the night. As she becomes more distant and her behaviour increasingly peculiar, Paul begins to suspect something more sinister than sleepwalking took place in the woods.

Treadaway and Leslie give captivating leading performances as a couple that takes new love to disturbing depths. With romance slowly giving way to terror, writer/ director Leigh Janiak puts her unique stamp on this intimate chilling thriller.
