Allison's boyfriend cheats on her and steals her retirement fund. So she leaves their home and finds a nice guy to live with. They're so virtuous they spend the first night in separate rooms. Nice guy's friends (who have sex in the street and on a forklift truck where they work) hold a (sex) party to welcome her to the neighborhood, but Nice guy and Allison have a more intimate party in the bathroom.
