In the early 1930's London, the black jazz group known as the Louis Lester Band is on the rise. Managed by the compassionate yet short-tempered Wesley Holt, the band lands a gig at the Imperial Hotel, thanks to the cunning journalist, Stanley Mitchell. They prove to be a hit, and their star begins to rise. Countless aristocrats-including the royal family-ask the band to play at parties, catching the eye of the ambitious American businessman Walter Masterson and his enthusiastic employee, Julian. But just as the band's success balloons, tragedy strikes, setting off a chain of events that may put an end to it all. From acclaimed writer and director Stephen Poliakoff (The Lost Prince), this ensemble mystery features an all-star cast led by Chiwetel Ejiofor (12 Years A Slave) and Matthew Goode (The Good Wife, The Imitation Game), and also stars Jacqueline Bisset, Tom Hughes, Angel Coulby, Wunmi Mosaku, and many more!
