Ciro Varelli is a Don Juan who works in a bookshop, a job to which he dedicates himself without too much effort while he spends his days in the company of his friends Leopoldo, a student outside the course, Flavio - who has a conflicted relationship with the opposite sex - and Pippo . Instead he has a great rival, Luca, and in an attempt to win the heart of the beautiful Beatrice he decides to make a bet with him. The rescue of a dog named Mazzarino will allow him to impress the wealthy Goldoni family, but not everything will go as planned.
