Driven to distraction by their dad, Dennis and Dee quit Paddy's and decide to go on welfare. Back at the bar, Frank is driving Mac and Charlie crazy. He's also beginning to treat them like sons.

After she's mugged, Dee takes boxing lessons from ex-pug Frank, who runs into an old nemesis at the gym. Meanwhile, Mac and Dennis enter Charlie in an underground street-fight match with hopes of making some money. And both Dee and Charlie need help, which they find in a pill bottle.
