In 1938, Rick and Rose Sinclair run an antique shop. One of Rick's shady friends offers him the deal of a lifetime on a large, beautiful hand that had been sculpted out of polished jade. The purchase drains their savings and incenses Rose, who is convinced this jade hand was stolen and that owning it will bring them nothing but trouble. Rose is soon proved right. Thieves break into the shop, steal the hand, and send it off to Phnom Penh, Cambodia. The Sinclairs will be broke if they don't retrieve the jade hand. With their friend Humphrey, a former Great War flying ace, they head for Cambodia. They are soon enmeshed in a gangster's plot to resurrect an evil Vedic goddess at an abandoned city along the Mekong River. Dangers abound as they fight off thugs, encounter a haunted rubber plantation, and realize the immense, supernatural power of the goddess known as Rudra the Destroyer.
