Inspired by the incredible true story of composer Joseph Bologne, Chevalier de Saint-Georges. The son of an enslaved African woman and a French plantation owner, Bologne (Kelvin Harrison Jr. in a tour de force performance) rises to improbable heights in French society as a celebrated violinist-composer and fencer, complete with an ill-fated love affair and a falling out with Marie Antoinette (Lucy Boynton) and her court.
