Het verhaal van twee broertjes van 13 en 15, wiens vader thuiskomt na 12 jaar weg te zijn geweest. Ze benaderen hem logischerwijs enigszins terughoudend, maar de vader wekt de indruk de gemiste tijd goed te willen maken.

After returning from the USSR, Tulyev was subjected to rigorous verification of his former "owners". He continues his work in Western intelligence, but already as a Soviet intelligence officer through the First Main Directorate of the KGB of the USSR. In a new capacity, he establishes the whereabouts of Hitler’s criminal Hoffmann, who was once sentenced to death, and helps the authorities arrest him. However, as a result of the conflict within NATO intelligence, Charlie Brighton, Hoffman's assistant, begins to hunt for him. At the same time, Tulyev manages to establish the identity of the murderer of his father, Karl Brockmann, with whom they crossed in the service of mercenaries somewhere in hot countries. He wants revenge, but, by an evil irony of fate, he must help prepare Brockmann for being cast as a spy in the Soviet Union.
