In the heart of the Pocono Mountains in Pennsylvania, a group of college students staying in a secluded vacation home enjoy one last weekend together before graduation.

In what was intended to be an idyllic weekend getaway, drama between friends and a brooding sibling rift threaten to send the weekend spiraling out of control.

Just when it seems like tensions are at their peak, a knock at the door propels the night into mayhem and brutality as a pair of homicidal maniacs besiege the home with bats and box cutters.
