Former German flying ace Heinrich Droop (Paul Hartmann) is given a postwar boost in the business world by Englishman Fred Keyne (Gustav Diesel) whose life Droop once saved. Appointed head engineer at Keyne's airplane factory, Droop seems destined for unlimited success. But things go horribly awry when our hero falls in love with Keyne's ex-chorine wife Blanche (Charlotte). Things look bleak when Blanche's former dancing partner blackmails the illicit couple, but all works out for the best in the film's gloriously unbelievable finale.
