The follow-up to Adam Wingard and Simon Barrett’s wildly popular You're Next, The Guest tells the story of a mysterious and devastatingly charming visitor, David (Dan Stevens of Downton Abbey) who arrives on the doorstep of a bereaved family claiming to be the best friend of their dead son, a young soldier who died in action. The Petersons welcome David into their home and into their lives, but when people start mysteriously dying in town, their teenage daughter Anna (Maika Monroe of It Follows) starts wondering if David is responsible.
