Dean Jones is mesmerizing in his portrayal of the apostle John in this drama. It's 96 A.D., and scores of Christians have been massacred all over the Roman Empire. John, the last living disciple of Jesus, takes action to stop the slaughter. He's now an 86-year-old man who's been forced to spend his remaining days imprisoned in a cave on Patmos, but despite this fact, he refuses to give up and subsequently changes the future path of humankind.
