During the First World War, before joining a squadron at the front in 1918, Herbillon (Jean-Pierre Aumont) has a liaison with Helene (Annabella), a married woman. The young man discovers that his mistress is none other than the wife of Maury (Charles Vanel), an aviator friend.
Annabella, Jean Gabin and Fernand Gravey star as a trio of circus trapeze artists. Both Gabin and Gravey love Annabella, but she has eyes only for Gravey. Seething with jealousy, Gabin plots revenge against his rival. He "accidentally" drops Gravey into a net during rehearsal -- but does he plan to do the same during a performance, when the trio works without a net?
