Hugo Vartan is an author looking for a juicy story for his next book. He comes across one in the form of the sister of his flatmate’s boyfriend, who has been hospitalised in a psychiatric ward for, seemingly, murdering her partner, beheading him with a knife and sticking his head on the steering wheel of her car.
Xabi and Sara break up just before their holiday trip. She leaves the house and Xabi stays alone. At first he doesn’t seem to be affected, but soon weird things will start to happen as he feels sick with a strange disease. When he finally understands what is going on he’ll have to make a decision that could change his life forever.
