The film begins with Betty (Isabelle Huppert) flirting at a gambling table with a traveling businessman on a convention and manages to get him to ask her up to his room. Once there the man falls asleep, knocked out by the drug Betty slipped into his drink before they left the bar. When Victor (Michel Serrault) arrives the two take money from the man's wallet and forge a check to a fake company it becomes clear that Victor and Betty make a living fleecing unsuspecting businessman and conventioneers at casinos and resort hotels in France, always stealing enough to make a profit but never so much that it puts hardship on the victim. This way it is embarrassing for the victim to report the crime and they don't miss the money so much. Betty and Victor have a comfortable relationship, he being old enough to be her father. When Betty states she needs a few days off before their next hit on a group of visiting Dentists, the two agree to meet at another resort to complete their next crime. Betty calls a few days later to say that she has already arrived at the planned location and has set up new mark Maurice Biagini (François Cluzet), an international banker. This is something Victor is uncomfortable with, especially because it includes stealing 5 million Swiss Francs for a crime syndicate. When they manage to switch off a metal brief case with one they have substituted, everything looks like they succeeded, until a gangster Monsieur K (Jean-François Balmer), looking for his money comes calling and Betty and Victor must do some fast thinking and talking.
