Summary: Heini Völker, son of communist parents in Berlin, is invited by the Communist Youth Organisation for a camping near Berlin, but he thinks the Hitlerjugend is more attractive, they've got more discipline and a better organization. His father wants him to become a member of the Communists, but he received an invitation to the HJ. A friend of his father, the local leader of the Communist youth, has arranged an attack on the HJ-rooms this evening. The HJ thinks, Heini is responsible for the attack. But Heini still wants to join the HJ, so he informs them about a planned bombing. The communists know after they lost their explosives, who is responsible for this, so Heini's mother who heard about it decides to kill herself and Heini with gas. Heini survives and becomes a member of the HJ. During an election campain he goes into his former quarter to deploy nazi-propaganda, but the Communists haven't forgotten his actions
