A night watchman on the Eiffel Tower wakes up to find the entire population of the city frozen in place.

A young man, unsuccessful in love, manages to leave his body and tours Paris, disembodied and invisible, playing practical jokes: a row of coats walks off from a hotel cloakroom; an unattended taxi drives itself away; a row of top hats appears on the pavement.

The almost financial ruined gentleman Georges Dewalter spends several days in Biarritz before going off in the Hispano-Suiza, a luxe car which was a present from friends. George becomes the lover of Stéphane Oswill pretending he is wealthy. Then Stéphane spends the remaining funds with which the now desperate George hoped to rebuild his fortune in Senegal.
