A man wakes up naked, deep in a dark cave. He's cold, in mud, and has no idea what brought him here, nor what happened to the dead man next to him. Around him, darkness and ruins of an ancient underground world, haunted by phantoms of an obsolete technology and by terrible, wild creatures chasing him. To find out who he is, Tolbiac (Clovis Cornillac) will have to get to the surface, through this strange network of galleries, abandoned by a mysterious organization called "Eden Log".
