After the fall of France, colorless Joseph Bridet determines to go to Vichy and ingratiate himself with the regime there as a first step towards escaping to England, only to discover that he agrees with the suspicious and pitiless world of the Petainists. 

In a state of permanent tension and relieved moral paralysis, Jean-Marie Thély, an anguished bystander confined to the margins of polite society, has based the whole of his existence upon the idea that he is unlike others. He derives his singularity from his origins as an illegitimate child; bounced from one condescendingly charitable household to another only to be rejected by the bourgeois families that raised him. Restricted to an ordinary education, barred from an officer's career, he is unable to do what he wants and eventually becomes trapped in a life of utter indecision.
