Charlie Chan, visiting San Francisco to make a speech, finds himself swept into one of his most puzzling -- and dangerous -- cases! A cult known as the Golden Horde is running a spiritual retreat, helping the disturbed and the depressed find inner peace. Benny Chan, who worked for the Golden Horde, is dead ... but the priceless treasure he carried has been recovered. Benny's sister is searching for the truth, and Chan agrees to help her. Ancient scrolls, shadowy villains, and an ancient organization with modern ties to organized crime are just the start. For this case will take Chan across the Pacific in search of answers ... and to the edges of the human psyche!
