"The beautiful light-skinned slave Isaura resists the harassment of her newly-married owner, Leôncio, son of the man who harassed her mother until she died. Leôncio sends Isaura to the fields to force her to yield, but Isaura flees instead with her father to Recife. There Isaura meets and falls in love with a well-to-do young man, Álvaro, but at a ball, she is recognized, and Leôncio takes her back to his farm, and orders her to marry Belchior, the gardener. But Leôncio is practically bankrupt, so Álvaro purchases his debts, freeing Isaura and leading Leôncio to commit suicide." --
