A man who travels accidentally back to the past and meets himself there. A naked girl in the middle of the forest. A scissor-wielding madman with his face covered by a pink bandage. A disquieting mansion on the toip of a hill. All of them pieces of an unpredictable jigsaw puzzle where terror, drama, and suspense lead to an unthinkable sort of crime. Who's the murderer? Who's the victim? In Nacho Vigalondo's time-jumping brain-twister, the future is never the same twice!
