Although the boys manage to avoid capture, Frank's old life is gone forever - he has now become a fugitive. Frank's father Kurt Korbach is stunned by the escape. Unknown to his son, Kurt is a Major in the Stasi. Convinced that Frank is innocent, he persuades his superiors that he alone can bring his son back. Together with the suspicious Colonel Frey - a time bomb waiting to explode - Kurt sets off to track down the runaway boys.
