Berlin, June 1944. Hugo Fischer is forced to work for the Nazi secret service, though he keeps his own dangerous secret from the Third Reich.

Faced with a series of high profile cases – the murder of a prominent Nazi couple, the suicide of a Reich journalist, and an accident in which fifteen Hitler Youth children died – he begins to suspect the incidents are linked.

Soon, Hugo finds himself uncovering a world of secrets and silent resistance. But when suspicion starts to fall his way, he finds himself walking a knife edge. To be found part of the conspiracy means death, and not only his own. But how can he betray those who stand up for what is right?
