A man's sour outlook on life brings about important changes in the lives of those who encounter him.

An auto mechanic unhappy with his lot in life plans to kill his wife and collect on the insurance policy he just opened on her. When the "accident" he arranged for her fizzles, he cancels the policy. As luck would have it, his wife becomes seriously injured in a real accident. Now he's fighting to keep her alive because her recently deceased father left her a small fortune that goes to charity if she dies.

After successfully murdering his wife, a man starts to think of himself as an expert at the craft. Soon, his friends and neighbors are dropping dead at a startling rate.
