Traffic problems as a result of the President's visit to Philadelphia makes it difficult for the gang to see the summer's biggest film, Thunder Gun Express.
Believing that they were slighted by a patron at another bar, the gang attempts to track him down so that they could get a little revenge. Charlie and Dennis inquire about the guy through others, while Mac and Dee resort to cyber-stalking. Left to his own devices, Frank also uses the internet in order to garner more business for the bar.
