11-year-old Andreu witnesses the last few seconds in the lives of a little boy and his father. The boy's last word is “Pitorliua”- the name of a mysterious ghost living in a cave in the woods. The local police, investigating the bodies that lie below the cliff in the woods, initially label it an accident but soon come to see it as murder. The only suspect is Andreu's father Farriol.
