Nike and Cooper divided their games between two main categories, "wargames" and "thematics". This was one of the first games published by them in the latter one, along with "La fuga de Colditz" or "Asalto al banco de Inglaterra". Set in the Cold War era, players enter East Berlin in order to find a personality who wishes to pass to the other part of the Wall. They have to find out who he is while evading military police and other hazards. Besides, one of the players is really a mole working for the Russians... The game is inspired by a tale by writer Arthur W. Landsbury.
