Javi is a teenage student so shy and clumsy that he does not know how to attract the attention of his classmate Sara, a geeky girl who is only interested in a literary saga about vampires.
Two years after the murder of his son and father, a retired hitman sets in motion a carefully crafted revenge plan against the killer: his own brother.
The Three Wise Men, fed up with Santa taking more and more prominence from them, have decided to confront each other without knowing that this war will awaken a much more dangerous common enemy, the Krampus, who had been inactive for centuries.
