Siblings, Brad and Lisa Carpenter, along with two lifelong family friends, Will and Vanessa, set out to cross Eastern Canada enroute to an annual family reunion. Their road trip takes them through the scenic, isolated countryside of New Brunswick, on a blistering hot summer day. They eventually make the decision to find an appealing place to stop halfway, and camp for the night. The group thinks they have found the perfect haven, when they are awakened by strange noises in the forest. What ensues is a violent disturbance by six masked assailants, without motive, without reason. The group find themselves living in a night of psychological games and physical terror, and as morning dawns; the reality of what will come is more terrifying than anything the group could have ever imagined.
