The screenplay by Tim Kazurinsky and Denise DeClue is based on the 1974 David Mamet play Sexual Perversity in Chicago. The film received positive reviews. It was remade in 2014. Plot In Chicago, Dan Martin and Bernie Litko, two 20-something friends and colleagues, discuss their sexual escapades. Later on, Bernie and Dan's recreational softball team, sponsored by local bar "Mother's," plays against a local advertising agency and wins. Attending this game with her girlfriends is Debbie Sullivan, who works at the advertising company and is sleeping with her boss, Steve. Debbie catches Dan's eye and they flirt at the beer keg. She and her friends, Joan and Pat, decide to attend the game's afterparty at Mother's, where Debbie again runs into Dan, with whom Pat flirts and Joan takes an immediate dislike to. They wind up back at Dan's apartment and sleep together, after which Debbie hastily leaves. The next day, Dan calls Debbie at work "about last night," and asks her out on a second date, to which she accepts. Afterwards, they again wind up in bed together and spend the following day exploring the city, where Dan reveals to Debbie that his dream is to quit his job at a restaurant supply company and open his own restaurant. They begin dating more seriously and move in together, much to the chagrin of Joan and Bernie, who dislike each other as well. As neither has ever been in a serious relationship before, they attempt to navigate cohabitation without much support from their friends. They experience much throughout their relationship: Dan being contacted by a former lover who is married with children, Debbie's boss Steve having difficulty accepting the end of their affair, Joan softening when she begins dating her new boyfriend Gary, a pregnancy scare, and Dan having difficulties with his boss, who wants him to stop providing supplies to the Swallow, an oldish diner owned by his client-turned-friend Gus. Despite having told each other the “L Word,” Debbie and Dan's relationship becomes strained. It reaches a boiling point at a New Year's Eve party at Mother's, where Debbie witnesses a drunken Pat making advances towards Dan, and Joan discovers her
