La Peste

During a stormy meeting at the town hall, Rieux, Laurence and Castel may alert the authorities and talk about a mutating plague bacillus, but nothing happens. Don't scare the tourists, that's the watchword. Tarrou suggests that Rieux create health brigades. The garbage collectors' strike was neutralized by the paramilitary militia and one of the strikers, Oumar Diop, was sentenced to one year in prison. Rambert plans to join Laurence in the capital, even if it means giving up his investigation. He does not have time: prefect Chauvat locks the city and speaks to Professor Richard about the application of a mysterious plan "D".

The entire city is confined under high surveillance. This is the first phase of the Darwin plan. Young Nora, her brother and her little sister, take refuge with Rieux who asks Lucie Ferrières, the pianist neighbor on the fifth floor, to take care of them. Without news of Laurence, Rambert wants to leave the city at all costs. Grand tells Rieux that the prefect intends to trigger the second phase of the Darwin plan, with disastrous consequences for the population...

Oumar Diop started a mutiny and took the director of the remand center hostage. Rambert agrees to negotiate with Diop in exchange for the release of Laurence, and on the condition that Rieux can come to the aid of the prison survivors with his health brigades. But everything does not go as planned. Taking advantage of Lucie's absence, Nora invited Jacky, her lover, a young militiaman devoured by ambition, to her home. He soon finds himself in possession of key information on the reality of the Darwin plan...
