凭本事单身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? He is involved in a wild chase both in France and Britain. He and his girl-friend get into scores of comic situations chasing the case stuffed with money. The character of Pierre Richard is victorious and becomes the owner of the revue unmasking the dirty plot of the villains. Side-splitting.
