Penelope Wilton (Match Point, Shaun of the Dead), Daniel Mays (Vera Drake, Atonement) and Sinead Matthews (Pride & Prejudice) star in this dark, twisted drama about three strangers who are willing to kill to protect what they have.

Jean (Wilton) is a professional house-sitter who has been assigned one last job before her retirement: the large and palatial Walden Manor. Quiet and peaceful, Jean minds the house alone. Then, one day, visitors come to the door: a pregnant young girl named Steph (Matthews) who is fleeing from her abusive boyfriend and Michael (Mays), the friendly stranger helping her run away but in their attempt to escape a brutal past, they spiral deeper into a violent present and set off a trail of blood that leads directly to the front door of Walden Manor.
