Synopsis: The legendary classic gets an unusual twist in this early adaptation by author Gore Vidal, starring Michael Rennie (The Day the Earth Stood Still). When Mr. Hyde is shot and killed in Dr. Jeckyl's laboratory and Jeckyl is nowhere to be found, his friend Utterson (Sir Cedric Hardwick) looks to the doctor's journal for answers to his mysterious disappearance. The journal reveals his friend's monstrous descent into madness as chronicled by Jeckyl himself. In an experiment to uncover the dual nature of man's soul, the good doctor has unleashed a monster from the pit, a murderous pleasure seeker he can't resist, who takes over his personality for nights of wanton debauchery and murder. Now only one last desperate measure can end the doctor's horrendous nightmare.
