Rut and her husband Bertil travel home by train after a holiday in Italy. Their marriage is unhappy due to Rut's changing moods and heavy drinking. While passing through the ruins of post-war Germany, Rut recalls an earlier affair with married military officer Raoul. Raoul forced her to abort their child, which resulted in complications, Rut's infertility and inability to continue her career as a dancer. Her friend and co-dancer Valborg, disgusted by men, turned to other women.
Bertil is still haunted by an earlier affair with widow Viola. While Rut and Bertil travel home, the film shows Viola's escape from a sadistic psychiatrist, her encounter with Valborg, who openly tries to seduce her, and her final suicide.
Meanwhile, the tensions between Rut and Bertil escalate, and Bertil seemingly kills Rut after a fight. Bertil awakens and realises that he imagined Rut's death. The couple decide to give their marriage another chance.

After the financial failure of Prison, the collaboration between Terrafilm and Bergman had ended. Svensk Filmindustri offered Bergman to produce his next film. Thirst was based on a short story collection published by Birgit Tengroth in 1948; Herbert Grevenius, who had already worked with Bergman on It Rains on Our Love, wrote the screenplay. Bergman asked Tengroth to star in his film, who helped him in finding the right tone in the lesbian scene between Viola and Valborg. Shooting took place between 15 March and 5 July 1949. Thirst premiered on 17 October 1949 in Sweden and on 30 August 1956 in the US.
