Hauled off to jail, but with Irma in love with him, Nestor is sentenced to 15 years' hard labor. Learning that Irma is pregnant, Nestor escapes from prison, with Moustache's help, and returns to Irma. He narrowly avoids being recaptured when the police search for him in Irma's apartment, but donning his old uniform, Nestor simply blends in with the other police. With the help of Hippolyte, Nestor arranges for the police to search for him along the Seine from which, dressed as Lord X, he emerges. Knowing he cannot be re-arrested for a murder the police now know did not occur, Nestor rushes to the church, where he plans to marry Irma. As she walks down the aisle, she begins to experience contractions, and they continue during the wedding ceremony. Nestor and Irma barely make it through the ceremony before she goes into labor and delivers their baby. While Nestor and everyone else is occupied with Irma, Moustache notices one of the guests sitting alone at the front of the church. Rising from his seat, and walking past Moustache, the guest is none other than Lord X! A clearly baffled Moustache looks at Lord X, and then at the audience. "But that's another story", he says.
