Maxwell and C.C. are going to Atlantic City for a business trip to meet with
Chevy Chase. Fran finagles it so that Maxwell decides to take the entire family on this trip. In Atlantic City, Niles' gambling addiction resurfaces. Fran tries to control his gambling habit. Fran's plan to help Niles leads to an inadvertent close encounter of a personal kind between Niles and C.C.
Chevy Chase has better fortunes at the gambling tables, especially when Fran arrives on the scene. He thinks Fran is bringing him good luck, which he wants to parlay into a private poker game he is having later in his hotel room. A jealous Maxwell misconstrues Chevy and Fran's evening as one of a romantic nature. Fran milks this for all it's worth, especially as she tells Maggie to let it slip to her father when and where she's going to be with Chevy.
