Women for Sale (1969)

Out of sheer boredom, some young scions from Hong Kong wealthy families have founded a very special club where only registered members are allowed. In this "shocker club" they indulge in pleasures that are as decadent as scary and brutal. While searching for his missing wife, American pilot Mike Anderson gets the club's address and meets erotic dancer Anne, who may be able to help him. Using the code name Bert Griffin, Mike discovers a girl trafficking operation that an influential consul runs with his syndicate. The women are drugged, transported to Singapore in coffins and brainwashed before being sold. When the young club members torture the consul's son to death and learn more about his father's criminal business, they find themselves on the hit list. Meanwhile, Mike has learned that his wife has also fallen into the clutches of the organization and is dead.
