Piuma, a failed cartoonist, lives in a small, dirty, messy studio apartment together with his dog, a German shepherd named Pinch. The boy and the dog live practically symbiotically, but as they have not paid rent for more than three months the two are evicted. On their way they meet Sophie, a young girl who is very uptight because she is about to get married to Claudio Guinzagli, a young man who is part of one of the richest families in the town. The situation further precipitates when Paolo, a wedding guest who has strong feelings for Sophie, comes across a cursed pond that turns him into a kind of Minotaur.
