Four egocentric friends run a neighborhood Irish pub in Philadelphia and try to find their way through the adult world of work and relationships. Unfortunately, their warped views and precarious judgments often lead them to trouble, creating a myriad of uncomfortable situations that usually only get worse before they get better.
When Psycho Pete, long lost member of the freight train, is released from the mental hospital, Dennis and Dee rush to get him recommitted while Charlie and Mac attempt to restore him to his former hard-partying form.
Charlie goes into overdrive when he's notified that the health inspector will be arriving that day. Meanwhile, the rest of the gang is trying to exploit a flaw in the air-miles reward system.
