Recent graduates of Georgetown University Alec, girlfriend Leslie, Kevin, Jules, and Kirby are waiting to hear about the conditions of their friends Wendy, a sweet-natured girl devoted to helping others, and Billy, a former frat boy and now reluctant husband and father, after a car accident. At the hospital, Kirby sees a medical student named Dale, with whom he has been infatuated since college.
The group gathers at their favorite college hangout, St. Elmo s Bar. Billy has been fired from the job Alec helped him secure and his marriage is unstable. At their apartment, Alec pressures Leslie to marry him, but she is convinced they are not ready. Kirby is telling Kevin of his love for Dale when Billy shows up, asking to spend the night as he cannot deal with his wife.
Kevin worries about his romantic life when Jules accuses him of being gay and loving Alec. When he visits Alec and Leslie for dinner, Alec confesses to Kevin that while buying lingerie for Leslie he had sexual intercourse with the saleswoman.
Billy and Wendy get drunk together and Wendy reveals that she is a virgin. She and Billy kiss but Wendy insists they just remain friends, especially since she realizes Billy is taking advantage of her crush on him.

Alec announces that he and Leslie are engaged, upsetting Leslie. She confronts him about her suspicions of his infidelity and the two break up. Alec is also angry with Kevin, who he believes confessed everything to Leslie. After the party, Jules gives Billy a ride home. As she is about to confide in him, Billy makes a pass at her. Furious, Jules throws him out of her car.
Still pursuing Dale, Kirby drives to the ski lodge where she is staying but learns she has a boyfriend. His borrowed car becomes stuck in the snow and Dale and her boyfriend invites him to come inside. The next morning, as Kirby prepares to leave Dale s cottage, Dale tells him she is flattered by his affections. He kisses her, and she does not resist.

Kirby fetches Billy, who landed a job at a gas station courtesy of Kevin, to calm Jules down. Billy convinces Jules to come back out.
Wendy moves into her own place, where Billy visits and informs her that he is getting a divorce and moving to New York City. The two make love as a going away present. At the bus station, the group gathers once more to say goodbye to Billy. Billy urges Alec to make up with Leslie but Leslie declares that she does not want to date anyone for a while.
