Katie Cassidy & Elizabeth Henstridge fear the Wolves at the Door in new trailer

Arrow meets Agents of S.H.I.E.L.D. with Wolves at the Door as it stars Katie Cassidy & Elizabeth Henstridge from the respective shows. The film is loosely based on The Manson Family’s Night Full Of Terror.

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.

John R. Leonetti (The Conjuring, Insidious, Annabelle) directs the film.
