This is basically a tale of one woman's (Vanessa Williams) rebellion against tradition and racism in the south. In a time when it is against the law to marry outside your race, Henriette (Williams), and Gerard (Bellows), fall in love and face trials of the law of the land of the day. They plan on moving to France where Gerard is from, where they can marry without any restrictions. Until Henriette's sister falls sick and they are forced to stay in the states. Henriette starts fighting with all her might for the rights of her people and her place in the church. I don't want to give away the ending so I will end this here.
