A respected doctor and his alluring wife are living large in the heart of Dixie.

They had money, the nice cars, the furs, the jewelry.

This doctor's worth a little in excess of $6 million.

Until their home becomes the scene of unspeakable horror.

He wanted $5,000 for the hit.

Twin sisters get caught at the center of the investigation.
