Rome. A solo bank and jewelry store robber always manages to escape the cops on a new maxi scooter. The crimes are the talk of the town, and the police commissioner on the case doesn’t know which way to turn. He asks for help from a Parisian friend known as The French, famed for having solved apparently impossible cases, who understands that the culprit behind these robberies is an unassuming blue-eyed woman no one would suspect: a math genius named Valeria, who knows Roman traffic like the back of her hand and aims to prove her worth through theft. Fascinated by her, The French will play a kind of chess game with Valeria, until he’ll be forced into a desperate gamble with the threat of arrest.
