Follow the Bitch (1996)

A group of single guys meet for their weekly, all male, all-night poker game. One of the regulars invites a woman (Liz) to join and she turns out to be a very good player. Things get more complicated when two of the guys (Ty and Gordon) confide to a third (Andy) that they're having affairs with each other's girlfriends. The host (Bill) tries to keep his weekly ritual intact as it begins to crumble around him.
