本讲述了某个偏僻荒凉的森林里,六个人在一处有腐尸的露天坟场旁醒来,却好像得了健忘一般的恐怖闹鬼故事。他们无处可去,被迫把神秘事件的线索拼凑起来,最终将带领他们走进惊人的结局,而不至于使真相来的太晚。A man 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.
