John Newland(Series director and host of "One Step Beyond") both directs and stars as Ellis Corbett, who, along with his wife Shelia(played by Antoinette Bower) is summoned to the home of his dying and eccentric sorcerer uncle Amos Wilder(played by Terence DeMarney) to inherit his estate, but with the condition that he follow his instructions exactly, which involves guarding his vault to prevent an evil rival sorcerer named Andrew Bentley(played by Reggie Nalder) from invading it for a most sinister purpose... Newland acquits his double duties here quite well indeed in a Gothic, atmospheric tale that is most memorable.
