Warren Maxwell, the owner of a run-down plantation, pressures his son, Hammond, to marry and produce an heir to inherit the plantation. Hammond settles on his own cousin, Blanche, but purchases a sex slave when he returns from the honeymoon. He also buys his father a new Mandingo slave named Mede to breed and train as a prize-fighter.

In 1957, director Harold Daniels was hired by producer Michael A. Ripps to oversee BAYOU, a cheaply made, overly melodramatic tale of swamp life. The low budget film starred a pre-MISSION IMPOSSIBLE Peter Graves, Corman regular Jonathan Haze, and the effortlessly bizarre Timothy Carey. But despite this eclectic cast, BAYOU was a major flop at the box office. So Ripps recut the film, adding an off-camera rape scene and a new, bloody conclusion to its climatic fight. Of even greater importance was Ripp's new title: POOR WHITE TRASH.
