Devil worshipping and Chinese tongs were the selling points of this ultra low-budget thriller produced at Willow Park, B.C., Canada. Assigned to quell a Chinatown crime wave, private detective Donegal Dawn (Raymond Lawrence) discovers that his best friend, Robert Rand (Nick Stuart), has become infatuated with Zenobia, a beautiful but strange white girl clerking in Chan Tow Ling's curiosity shop. The girl, however, is frightened of something and warns Robert that they can never be together. That night, the lovesick youngster steals into the basement of the shop where he observes Zenobia officiating a weird ceremony. When the worshippers, known as the Order of the Black Robe, discover Robert's snooping, Zenobia either cannot or will not help him and he is led away. Dawn, meanwhile, tracks the cult to a hideout in the mountain. After a furious donnybrook at the top of a cliff, the detective is able to save both Robert and the entranced Zenobia.
