In this French frightener, a man (Clovis Cornillac) wakes up to find himself at the bottom of a cavern. But this is no ordinary cave; it appears to be the abandoned labs of a company called Eden Log. However, the underground labyrinth isn't entirely empty. A creature prowls the halls, and the man must do all he can to escape its clutches.
A man wakes up deep inside a cave. Suffering amnesia, he has no recollection of how he came to be there. Tailed by a mysterious creature, he must continue through this strange and fantastic world to find his way to the surface.
