Desire in the Dust (1960)

Lonnie Wilson, the son of a toothless sharecropper, Zuba Wilson, returns to small southern hometown after spending six years on the chain-gang for killing Colonel Ben Marquand's son in an automobile accident. He revives his love affair with Melinda Marquand, who is now Mrs. Melinda Thomas, since she married Dr. Ned Thomas, while Lonnie was serving time, in her place, for the accident she caused. Somewhat miffed about all this, Lonnie incites Dr. Ned about his wife's infidelity, which Dr. Ned verifies when he catches Lonnie and Melinda in a semi-torrid embrace in Colonel Marquand's hunting lodge. Melinda, looking for an explanation for this situation, shoots and wounds Lonnie to defend her innocence by claiming she was being raped. Colonel Marquand,who had bribed Lonnie to take the blame for his daughter, uses her story to try and have Sheriff Wheaton kill Lonnie, and put an end to all this mess. But there is another reel or two before this mess ends.
