Jan-Erik Widgren meets the lonely Bertha Olsson, a woman struggling with alcoholism. Though Bertha is already linked to Caligula, Jan-Erik's heartless teacher, she begins a relationship with the boy anyway. When Caligula learns that Jan-Erik is having an affair with Bertha, he begins to torture his student psychologically. He reserves his cruelest behavior for Bertha, however, which results in a tragic turn of events.
