Les deux 'Monsieur' de Madame

A quiet, middle-aged man spirals into obsession and paranoia when a charismatic look-alike moves in next door, featuring the exact same face—and a full head of hair.

To help his divorced neighbor claim a substantial inheritance, a family man poses as her husband. The ruse spills over into his career in advertising, and his recent promotion relies on his wholesome and moral appearance.

The whole intrigue is centered around carte-blanche documents kept in a vault. Whoever fills in the blank becomes the owner of a revue. Big money is involved. The nephew of the owner of the vault is trying to cheat his uncle and have his name in the documents. Everything is even more complicated because the manager of the bank has a finger in the pie, too. Who but a humble bank-teller (Pierre Richard) will ruin the scheme?

A pompous grocer’s assistant in Marseille annoys a visiting film crew so much that they prank him with a phony acting contract; believing it to be real, the “schpountz” heads to Paris for his new career.

After getting screwed over by life (again), two losers decide that enough is enough. Using stolen ski masks and stolen toy guns, they take hostages in their local bank, holding them for ransom. Things go well until the hostages learn what's going on, and demand a piece of the action for themselves.
