In Claude Chabrol's fiftieth film, two lifelong partners in crime, Betty (Isabelle Hupert) and Victor (Michel Serrault), operating out of a small RV, criss-cross the country, hopping from convention to convention and scamming bourgeois businessmen out of petty sums of money. They make enough, however, to maintain a comfortable if elusive lifestyle. When Victor discovers that Betty has been carrying on her own scam for over a year, the blurry lines between secrets and lies break down. As the scheming duo go ahead with Betty's complicated scheme to steal a breifcase from a man (Francois Cluzet) who holds the treasure of a multinational corporation, the film kicks in to high gear. Filled with switched identities, changing allegiances, suppressed romances, and switcheroos, the elaborate story, which takes viewers from the Swiss Alps to the tropics, leads to an operatic and surprising climax. True to Chabrol's style, the ambiguous and compelling psychology, always in flux, propels the drama of the film forward even more than the actual danger of the plot.
