Felix Unger (Jack Lemmon) checks into a fleabag hotel room and attempts to kill himself by jumping out the window, but he can’t get the window open and ends up pulling a muscle in his back. Limping back on the street he tries to get drunk and ends up hurting his neck when he throws down a shot. Finally, he stands on a bridge, contemplating jumping into the river.
Meanwhile, in the pig-sty Upper West Side Manhattan apartment of divorced sportswriter Oscar Madison (Walter Matthau) on a hot and sticky evening, Oscar and his buddies Speed (Larry Haines), Roy (David Sheiner), Vinnie (John Fiedler), and Murray the cop (Herb Edelman) are playing poker and discussing their friend, Felix Unger, who is unusually late to the game. Murray’s wife calls and tells him that Felix and his wife Frances have split up. As they are discussing what to do, and worried that Felix might try to commit suicide, Felix arrives not knowing that his friends already know that his wife has kicked him out of the house.
Felix eventually breaks down crying and his friends try to console him. Oscar then suggests that Felix move in with him, since Oscar has lived alone since he split up with his own wife, Blanche, several months earlier. Felix agrees, and urges Oscar to not be shy about letting him know if he gets on Oscar’s nerves.
Feeling awful about throwing Felix out, and not knowing where he has gone, Oscar assembles his poker buddies to search New York City for Felix in Murray’s police car. After searching for hours, they return to Oscar’s apartment to find out that Felix has moved in with the Pigeon sisters. Oscar and Felix apologize to each other, and realize that a bit of each has rubbed off on the other, with each being a better person for it.
