Norman Frayne is blackmailed by Al Revnel. His buddy went to prison for 12 years and kept quiet about Normans involvement in the crime. Al wants money and forces his way into Normans house. Al abuses his power over Norman asking for a lot money and frequently. To make matters worse, Norman thinks Al is after his wife.
When Norman wrongfully thinks his wife is going on a trip with Al, he confesses to her. But his wife loves him and was going on the trip with a friend.
Norman had planned to kill Al, seeing no other way of getting rid of him. Only...(well I better not spoil the end!).
