Irma la Douce

The film version of Irma La Douce (which means "Irma the Sweet") tells the story of Nestor Patou (Jack Lemmon), an honest policeman who finds a street full of prostitutes in a popular area in Paris. After reporting the ladies to the police inspector, who was aware of those prostitutes and lets them off by accepting bribes, he fires Nestor. Drowning his sorrows at the local bar, Chez Moustache, Nestor becomes close friends with Irma La Douce (Shirley MacLaine), a popular prostitute. After Irma dumps her pimp boyfriend, Nestor moves in with her, and he soon finds himself as Irma's new pimp. Jealous of the thought of Irma with other men, Nestor comes up with a plan to stop Irma's prostitution. He dresses up as an elderly English lord and impresses Irma by giving her 500 francs twice a week. Nestor is able to borrow the money from the owner (Lou Jacobi) of Chez Moustache, who is the mastermind of Paris and decides to help Nestor. But he soon finds out that it's not all that it's cracked up to be.
