Here's the synopsis again:
Written and directed by award-winning filmmaker Stephen Poliakoff (The Lost Prince, Shooting The Past), the five-part series follows the Louis Lester Band as they find fame amongst the parties and performances of upper class society in the capital. Initially shocked by black musicians performing in polite society, many recoil, but London's progressive socialites take the band under their wing.
When the band's manager Wesley becomes too demanding to the hotel in which the band performs he is deported, forcing the rest to move on without him. The musicians play for the Prince of Wales who elevates their status to the heights of early pop fame. But they become entangled in the shadowy world of socialites, which results in the suspected murder of the band's singer Jessie. The walls begin to close in on Louis and the other members until they realise that escape from England may be their only chance for safety.
Let me warn you, though, that this trailer could potentially be considered one huge spoiler. So watch at your own risk . . .
