With Charlie under his wing, Frank cleans up so he can get his hands dirty and help out his old company with one last big merger. While an unwritten rule of the bar gets the rest of the gang caught up in a case of mistaken identity.

Every member of The Gang has something to celebrate at Guigino's, Philly's finest eatery. But when Mac and Dennis' private dinner is interrupted by an unexpected sighting of Frank and Charlie, the in-fighting begins. Dee turns up at a table for one, and over the course of the night, the "one-ups-manship" soars to new heights.
