[1][2][3] Oscar Pettinari is a young hick from the suburbs of Rome, who gravitates around Cinecittà trying rather unsuccessfully to impress his acquaintances as well as the producers with the tales of his experiences as a stuntman in Rambo-like action movies.

While boasting among bystanders about his supposed previous jobs in the movie industry, the disappointed Oscar meets by chance the whimsical lawyer Giangiacomo Pigna Corelli in Selci.

The confident laywyer impresses the looser Oscar, who accepts on the spot his suggestion to stage a fake incident and play the victim of a car crash with the foreigner movie producer, in order to blackmail him into either paying damages or offer him a chance as an actor.

At the same time, Oscar is grappling with the increasingly frequent and more extreme quirks of his lawyer, who makes him reject a favorable settlement proposal with the movie producer and wants to bring the attempted scam to court.

It turns out that in reality he is nothing more than a mythomaniac, of noble origins but prone of continuous episodes during which he convinces himself and some naive and unlucky victims to be some kind of expert - in this case a lawyer, previously a dentist or a veterinary, and after the last crisis a ballet choreographer.
