Historical film drama, set in late 1700s London, inspired by the true story of Dido Elizabeth Belle, the illegitimate mixed-race daughter of Royal Navy captain, Sir John Lindsay. Raised by her aristocratic great-uncle, Lord William Murray, 1st Earl of Mansfield, and his wife, Belle's lineage affords her certain privileges, yet the colour of her skin prevents her from fully participating in the traditions of her social standing. Left to wonder if she will ever find love, Belle falls for an idealistic young vicar's son bent on change, who with her help, shapes Lord Mansfield's role as Lord Chief Justice to end slavery in England.
