Middle aged bourgeoisie couple lives a loveless life along with their beautiful eighteen year old daughter. The man has a passionate desire for the girl who in fact is not his real daughter but the fruit of an affair of the woman early in the marriage. This leads to tragic events.

Joe, fed up with his in-laws, runs away from home. Enjoying his newly gained freedom and his father-in-laws credit card, he seduces a number of girls, buys them expensive presents and wines and dines them. His joyride soon ends when he finds out that his wife - and several other girls - are pregnant.
