A mine that explodes in the middle of the Moroccan desert and, years later, a stray bullet that lodges in his brain... Bazil hasn't had a lot of luck with weapons. The first left him an orphan, the second could cause him to die suddenly at any moment.
When Bazil comes out of hospital, he finds himself without a home. As chance would have it, this gentle dreamer with an overactive imagination, is taken in by a gang of truculent vagabonds whose aspirations and talents are as diverse as they are surprising. Remington, Calculette, Fracasse, Placard, Môme Caoutchouc, Petit Pierre and Tambouille live in a veritable Ali Baba's cave.
One day, when passing by two imposing buildings, Bazil recognizes the logo of the two arms manufacturers who caused his misfortunes. Assisted by his gang of crazy friends, he decides to take revenge.
One against all, cunning little folk against powerful and cynical industrialists, our vagabonds perform again, with an imagination and fantasy worthy of the famous French comics character Bibi Fricotin and Buster Keaton, the combat between David and Goliath.
