Paris, June 1940. The de Gaulle couple is confronted with the military and political collapse of France. Charles de Gaulle joins London while Yvonne, his wife, finds herself with her three children on the road of the exodus.
Wallflower camerawoman Caty (Marie Gillain) is three years into her career and residency in the French capital with little to show for it in the friend category, never mind the fact she is hopelessly single. While on the job filming an interview with a prostitute, Caty gets a tip from the hooker for a quick and profitable money-making possibility. Following up on the lead, Caty meets the handsome Jean (Vincent Elbaz) who offers to pay her to film him while he robs a store. After some perfunctory soul-searching, Caty impetuously decides to take the offer. This start in crime leads her into Jean's gang of criminals, which she rather quickly becomes a member of. As the thieves tend to spend their loot about as quickly as they accumulate it, they begin planning an enormous caper that will enable them to live more comfortably - if they manage to survive its undertaking.
