A hopeless romantic man (Gleeson) thinks he's found true love with an older woman (Applegate) - only to learn that she's married and that his fling is merely an instrument of revenge against her neglectful husband (Church).

He threatens to blackmail her by telling her husband but his plan backfires when the husband decides the best way to get back at his wife is to move in with him and adopt the slacker's life of debauchery.
