Berlin 1935
On the eve of the Olympics, musician Willie Cooper is banned from performing her beloved jazz. With her half-German niece and nephew in need of food and shelter, she turns to the music underground to earn money. Each illegal gig brings the feared SD closer to her people, who are needed for an experiment only spoken of in feared whispers on the streets.
British Intelligence Agent Klaus Hummer's mission is to observe and report as a journalist for Das Schwarze Korps, the Nazi's premiere newspaper. The immersion into Nazi propaganda and culture reveals an alarming agenda that will put him on a path to sacrifice the life of a beautiful jazz singer in favor for an assignment that can not fail.
