At a Catholic public school, Benjamin Stanfield is tired of being the teacher's pet and decides to play a practical joke on his form master Father Goddard. In confession, Stanfield tells Goddard that he has accidentally murdered his friend Blakey and buried him in the forest. When Goddard investigates the matter, he finds a buried scarecrow. Goddard is outraged, but, due to the seal of confession, he knows he cannot expel Stanfield. Shortly after, Stanfield once again enters the confession booth, telling Goddard that what before was a practical joke, he has now made happen. In disbelief, Goddard once again goes to the forest to investigate the matter. This time, he discovers Blakey's dead body. The plot soon thickens as Stanfield's fellow student Arthur Dyson mysteriously disappears. In confession, Stanfield claims to have murdered him too. Outside of confession, he denies everything, leaving Goddard powerless. Confused by murders he is not allowed to talk about, Father Goddard starts to go mad. He eventually murders Stanfield with a spade, only to discover that his pet student never confessed to anything but the initial scarecrow prank. After that, another student, who is a great voice impersonator, decided to take a hideous revenge on Goddard, taking advantage of the confession booth where one whispers and cannot be seen.
