The young communist Artur Becker fights with the Interbrigades against the Franco putschists during the Spanish Civil War. He had experienced his baptism of fire in Germany at the time of the Weimar Republic during the Kapp Putsch. He was seriously wounded and arrested. After an unsuccessful escape attempt, he was interrogated several times by Spanish and German putschists and then shot.
