The Alfred Hitchcock Hour

Bill and Janet Nelson move into a new home next door to a family named Stander. Unfortunately, the Stander's son Eddie is a homicidal monster. Eddie kills the Nelson's dog and then runs a trip wire across the cellar stairs that almost causes Janet to break her neck. Bill knows that Eddie is responsible, but Eddie's father Jack Stander won't do anything. Jack controls the boy's life with an iron hand. It is later revealed that Eddie is not the source of the problems. Eddie, himself, is a victim of parental misunderstanding.
