1933. A body has been found on a luxury airship en route from Berlin to Rio de Janeiro. Police Detective Bruno Brckner, travelling on board, is immediately asked to investigate - and soon discovers that the murdered man was not the proud Nazi he claimed to be. What's more, he was carrying a stash of banned 'degenerate' material. As Brckner interviews his fellow passengers - a wealthy baroness, an antisemitic doctor, a debonair Englishman - he realizes that each of them has something to hide. Uncovering the truth will reveal a story of secret identities, forbidden love and revenge, where nothing is as it appears.
