Mattia Manfredonia

Marco, Tato, Serena, and Leo are nine years old, and they are inseparable friends, ready to defend each other from their schoolmates’ bullying. On the evening of Marco's birthday, all four find themselves together to blow out the candles and unknowingly make the same wish: become adults. In one night's time, they find themselves magically the same age as their parents, but with the same behaviour and thoughts they have as kids.

Francesco, a charming and ambitious separated father, picks up his son Mattia from school to spend "their" day together. He manages to transform a perfectly normal and seemingly quiet afternoon into a fun, special, and almost outlandish adventure. However, everything changes in the evening when Francesco drops Mattia off at his ex-wife's house and has to return to his everyday reality—and the bitterness of solitude.
