Betty and Victor, a couple of con artists, (Are they related? Married? We never know) are travelling through France in their motorhome, scraping a living through an occasional scam. But when they run into young Maurice, who's apparently delivering a bag full of money to Guadeloupe, they become embroiled in an international swindle. Who is on whose side, and who can trust who? With as many turns as any David Mamet script this delivers a brutal and cruel final climactic twist.
