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
Most attempts at tension are telegraphed so far in advance, they might as well be stamped with the previous week's postmark, while Cassidy and co are portrayed as such irritating "beautiful people" that some may find themselves reluctant to root for them.
Delivers some stellar performances & a genuinely terrifying story, but is largely let down by the filmmaker's inability to understand that there are limits to what can & cannot be shown on screen when it comes to the retelling of real life murders.
