It is 1940. Austria has been annexed, the German war machine has invaded Poland and is advancing west toward France. In Berlin Kurt Muller, an Abwehr signalman, discovers a colleague lying dead at his radio receiver. The criminal police dismiss the death as suicide, but Kurt is not convinced. Following a trail of mysteries, Kurt witnesses several atrocities that expose the Nazi regime for what it truly is. When the trail leads him to the German resistance, he faces the most difficult choices of his life. He must choose between his country and his family, between his duty and his conscience, and finally, between love and death.
