Much like Pride and Prejudice, Belle weaves together the story of the relationship between sisters with a romance that flies in the face of convention. Dido Elizabeth Belle is a biracial heiress in 18th-century England, where she lives, along with another cousin, with their powerful uncle and aunt. Trapped in a strange position, as a Black woman who also is wealthy in her own right, Dido struggles with what her future will look like. As her uncle, a powerful judge, is required to preside over a case that could decide the future of slavery in the British Empire, Dido crosses paths with a fervent young lawyer who sees her as no one else ever has.
