I feel like I’ve done some things that I wasn’t proud of—that I might not like the man I was.

What would you do if you woke up in a mass grave with no memories? That’s exactly the situation faced by John (played by District 9’s Sharlto Copley), the central character in Open Grave, the latest thriller from Tribeca Film. As John stumbles upon a group of frightened strangers (including The Vampire Diaries’s Joseph Morgan and German star Thomas Krestchman), he must help them discover their own identities even as he searches for his own. Throughout, the presence of the unknown killer (or killers) threatens to destroy their new alliance.Open Grave hits VOD and digital platforms on December 24 and select theaters on January 3, 2014.
