SYNOPSIS:

Young newlyweds Paul (Harry 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 behavior increasingly peculiar, Paul begins to suspect something more sinister than sleepwalking took place in the woods.

Treadaway (CONTROL) and Leslie (HBO’s “Game of Thrones”) give captivating leading performances as a couple that takes new love to disturbing depths. With romance slowing giving way to terror, writer/director Leigh Janiak puts her unique stamp on this intimate, chilling thriller.

Honeymoon is the feature directorial debut for Janiak, who previously worked as an assistant on movies like Mirror Mirror, It’s Kind of a Funny Story, and Europa Report.
