When wealthy plantation owner Cornelius Allen marries off his daughter Clarissa, he presents her with a wedding gift: a young slave woman called Sarah. It just so happens that Sarah is Allen's daughter as well, the product of a long-term sexual relationship with his slave Emmeline. When Clarissa's husband rejects her newborn son as illegitimate and sends Clarissa and Sarah back to the Allens, their return sets in motion a series of events that will destroy the once-powerful family.
