Betrayed by an informant, Philippe Gerbier finds himself trapped in a torturous Nazi prison camp. Though Gerbier escapes to rejoin the Resistance in occupied Marseilles, France, and exacts his revenge on the informant, he must continue a quiet, seemingly endless battle against the Nazis in an atmosphere of tension, paranoia and distrust.
The movie is based on the true story about a group of children, barely teenagers, who joined Yugoslav Partizans after losing their families in WW2. At first, Partizans want to get rid of them, but later they are joining combat ranks. Among them, Bosko Buha would become a legend because of his skill in destroying enemy bunkers.
