A prominent Mississippi heart surgeon dies under mysterious circumstances. In the sleepy Bible Belt town of Hattiesburg, what happened to Dr. David Stephens turned out to be the stuff that scandals are made of. His wife said he probably killed himself, but she was arrested for murder. 48 Hours' investigation with Correspondent Harold Dow takes us inside the operating rooms, courtrooms - and the bedrooms - of a town where "everybody knows your name." It's a classic tale of infidelity, gossip, tragedy - and possibly even murder.
