Some secrets cannot stay buried.
“A man (Sharlto Copley) wakes up in a pit of dead bodies with no memory of who he is or how he got there. Fleeing the scene, he breaks into a nearby house and is met at gunpoint by a group of terrified strangers, all suffering from memory loss. Suspicion gives way to violence as the group starts to piece together clues about their identities, but when they uncover a threat that’ s more vicious—and hungry—than each other, they are forced to figure out what brought them all together—before it’ s too late.”
Are those people former zombies who get cured somehow?
There’s also a film poster:
The moment you wake up, the nightmare begins.
Anyway, the release date of Open grave is set to January 3, 2014.
