A group of teenagers take a trip to an isolated summerhouse in the countryside. What starts as a peaceful getaway turns into a horrific nightmare when a masked man begins to terrorize them in the most gruesome ways.

In town for a job interview, a young woman arrives at her Airbnb late at night only to find that it has been mistakenly double-booked and a strange man is already staying there. Against her better judgement, she decides to stay the night anyway, but soon discovers that there is much more to be afraid of in the house than the other house guest.
