Berthe, very moved by the film with a sulfurous reputation The Last Tango in Paris, goes to the address where most of the action is located, a building overlooking the aerial metro on the Bir-Hakeim bridge. Reality suddenly seems to follow fiction when she discovers not only an apartment posted for rent but also that a man prostrate in a corner seems to be waiting for her. Hoping for the same steamy embrace as in the film, she finds that the man is in fact only concerned with the faults of the accommodation. Trying all the same to start a passionate affair with him, she learns that the man suffers from libido disorders.
