1997 film
The Swindle (French: Rien ne va plus) is a 1997 French crime comedy film, directed by Claude Chabrol that stars Isabelle Huppert and Michel Serrault.
The film initially focuses on a duo of con-artists who habitually prey on delegates in business conventions. They satisfy themselves with stealing only small amounts of each victim's property. The woman of the pair eventually decides to perform a more ambitious heist, and the duo steals millions from money launderers. When apprehended by the gangsters, they fool them by returning only part of the stolen money. The con-artists now have to face each other for possession of the remaining money.
