Four friends gather at an elegant home during the Summer of Love, 1969. Unbeknownst to them, deadly visitors are waiting outside. What begins as a simple farewell party turns to a night of primal terror as the intruders stalk and torment the four, who struggle for their lives against what appears to be a senseless attack.
