When honest Parisian policeman Nestor Patou (Jack Lemmon) is fired from the force for raiding a brothel and upsetting both the police and the Pimps union, not to mention inadvertently netting his station's chief inspector at the brothel, he takes on the job of being pimp to prostitute Irma la Douce (Shirley MacLaine). When Nestor falls in love with Irma, he finds that he doesn't like the thought of Irma seeing other men, so he devises a plan to guarantee that he is her only customer.

No. Irma la Douce is based on the French stage musical of the same name by Alexandre Breffort (play) and Marquerite Monnot (music). It was adapted for the screen by Romanian-born comedy writer I.A.L. Diamond and Austrian-born film-maker Billy Wilder. The film version of Irma la Douce, however, is not a musical.

At the very beginning of the movie, it is explained that "Irma la Douce" is French for "Irma the Sweet".

When Nestor learns from Moustache (Lou Jacobi) that Irma is pregnant, he breaks out of prison and dashes back to Irma's loft. He asks her to marry him, even though Irma tells him that the baby is Lord X's, not his. He eludes the police when they come looking for him by dressing in his old uniform and pretending to be one of them. On a tip from Moustache, Hippolyte (Bruce Yarnell) squeals to the police and leads them to the spot along the Seine where he saw Nestor drown Lord X only to find Lord X emerging from the water and quite alive. During the wedding ceremony, Irma goes into labor and has to be escorted out. The police catch up with Nestor but, instead of arresting him, they offer him his old job back. Nestor hears a baby cry and learns that he has a daughter. In the final scene, while Nestor sits with his wife and child, Moustache wanders back into the church and is surprised to see Lord X rise from a pew and walk past him. "But that's another story," he says.

Given the timeline and the fact that Irma basically stopped working as a prostitute after meeting Lord X, it's insinuated in the movie that the only time Irma could have gotten pregnant was the night that she raised Lord X's passions with her sex therapy.

Some viewers conclude that there really was a Lord X, others see it as a touch of mystery à la Alfred Hitchcock, some have suggested that Moustache always was a bit off his rocker, but most see it simply as a nonsensical, screwball ending to a nonsensical, screwball comedy.

Billy Wilder (1906-2002) has an extensive list of movies that he has either written, directed, and/or produced. Viewers who have seen Irma La Douce also place Piso de soltero (1960) at the top of their list since it's an earlier cooperation between Jack Lemmon and Shirley MacLaine. Other Wilder films that star Jack Lemmon include Una Eva y dos Adanes (1959) and ¡Avanti! Amantes a la italiana (1972). Also recommended are Sabrina (1954), La comezón del séptimo año (1955), Testigo de cargo (1957), and Uno, dos, tres (1961).
