But that careful balance is upended when an unwelcome shadow from her past, David (Tim Roth) returns, carrying with him the horrors of Margaret's past. Battling her rising fear, Margaret must confront the monster she's evaded for two decades who has come to conclude their unfinished business.

Writer-director Andrew Semans delivers pure havoc one moment and feelings of deep familiarity the next, creating a film that promises a gripping emotional journey fused with a grand guignol-style living nightmare.
