The plot centers on the handsome Belgian sailor Georges Querelle, who is also a thief and murderer. When his ship, the Vengeur, arrives in Brest, he visits the Feria, a bar and brothel for sailors run by the madame Lysiane, whose lover Robert is Querelle's brother. Querelle has a love/hate relationship with his brother; when they meet at La Feria, they embrace, but also punch one another slowly and repeatedly in the belly. Lysiane's husband Nono tends bar and manages La Feria's underhanded affairs with the assistance of his friend, the corrupt police captain Mario.
