An all-knowing interlocutor guides us through a series of affairs in Vienna, 1900. A soldier meets an eager young lady of the evening. Later he has an affair with a young lady, who becomes a maid and does similarly with the young man of the house. The young man seduces a married woman. On and on, spinning on the gay carousel of life.

Six people travel by overnight train from Marseilles to Paris. When they arrive, one of them, a young woman, is found dead in a sleeping berth. The police, led by Inspector Grazzi, investigate the other five passengers, suspecting that one among them was responsible. However, as the investigation is stepped up, the others start turning up dead. It's up to the remaining two to solve the case, lest they become the next victims.
