35-year-old Tripp still lives with his parents Al and Sue in Baltimore. His best friends Demo and Ace also still live in their parents' homes and seem proud of it. Tripp has many casual girlfriends. When he’s tired of them, he invites them to “his place"—and when they realize he still lives at home, they promptly dump him.
Al and Sue are fascinated when their friends, whose adult son recently left home, reveal they hired an expert to get him to move out. The expert is Paula, who believes that men continue to live at home because they have low self-esteem. Her approach is to establish a relationship with the man to build his confidence, then transfer his attachment from his parents to her.
