Two women, Léa and Clotilde, with two men, Ludovic and Papillon, form a nice quartet of crooks. Their targets: pharmacists, diamond dealers, and gogos of all kinds who respond to enticing classified ads. Business is booming, but the police are watching. Commissioner Masson will eventually arrest them, but, ironically, for a matter of which they are totally innocent.
