Fuochi d'artificio

1944, Piedmontese Alps. Marta and her father are stopped by a German patrol and he entrusts her with a secret envelope, because children are not searched. Davide, her brother, has a brilliant idea: to help the partisans by exploiting their young age. Thus, the mysterious partisan Sandokan is born.

The partisans hiding in the mountains need food, and Marta takes advantage of this to bring her best friend Sara into the group, since Davide has already recruited Marco. The four embark on their first secret undercover mission, but Marta can't stop thinking about her older brother Matteo, who is being held prisoner in the enemy fort.

Marta and Davide enter the German stronghold and gather crucial information for the partisans. But the new general puts a bounty on Sandokan, and Sara risks being discovered.

A Nazi-Fascist reprisal stops the young people and reopens old wounds in their grandparents that have never healed. Marta discovers the truth about her mother and finds the courage to fight back, but in Praverso she and Sara fall into a dangerous ambush.

While her loved ones search for her, Marta searches for Sara, who she lost sight of during the German attack. With her is Vittorio, a partisan and friend, to whom she confides her dream of sabotaging the enemy's arsenal.

Marta and Sara return to the mountains and reunite with Davide and Marco. It's time to implement Marta and Vittorio's crazy plan, which could bring peace once and for all.
