Edouard and Félix work in a real estate agency. One day, they are threatened with dismissal if they don't manage to sell a very isolated house to an elderly, silver and somewhat unusual Englishwoman. In the house, they discover a corpse. The visit is spent dragging the corpse from room to room, cupboard to chest, so as not to frighten the otherwise impressed buyer. But the corpse disappears. He has to be found before the deed can be signed. The two salesmen become detectives, tracking down the dead man's many female acquaintances. All the seducer's conquests are sifted through, to find the one who left her jewels at the scene of the crime.
