Sick (2008)

After having a fight with her boyfriend, Julie gets out of the car and starts walking in the middle of nowhere. The first thing she finds after a while is a small cabin with a retarded huge guy sleeping outside on a chair. He wakes up and starts chasing her, until he grabs her and hits her. Hours later, she wakes up inside the cabin, tied to the wall. It doesn't take long for her to realize that she is trapped there by a whole family of SICK people. It is unclear what their intentions are... She manages to call her boyfriend... When he arrives at dawn, he is going to face a weird surprise.
