At a Catholic public school, Benjamin Stanfield (Dominic Guard) is tired of being the teacher's pet and decides to play a practical joke on his form master Father Goddard (Richard Burton). In confession, Stanfield tells Goddard that he accidentally murdered his friend and buried him in the forest. When Goddard investigates, he finds a buried scarecrow. Shortly thereafter however, real dead bodies begin to turn up. In confession, Stanfield takes credit for the murders. Confused by evidence he is not allowed to disclose, Father Goddard begins to go mad and eventually murders Stanfield with a spade, only to discover that another student is responsible for the brutal crime spree.
