Mickey and Francis Fitzpatrick, each in their own fashion, have tried to live by their father's rule: "You've got to do what makes you happy first." Mickey is a cab driver, happily slacking off until he meets Hope, a beautiful graduate student, and impulsively marries her the next day. Francis, a responsible Wall Street broker, finds himself unable to decide between his loving wife and his mistress. The brothers begin to realize that the lessons their father taught them about happiness may not be the best advice about love.
