A former left-wing V-man comes clean, wants to clear the air. Actually, something like this doesn't happen. It took many preliminary talks and several attempts before Jan P. actually sat down in front of the camera.

STRG_F reporter Felix met Jan P. and asks himself: What does such a double life do to people - to the traitor and the betrayed?
