The Master Beater (1969)

Hawk, a brutal sadist, derives his pleasure from the pain and degradation he inflicts upon others. Skilled at exploiting human weakness, he forces men to sell their wives into white slavery for a bag full of a white, powdered drug. No woman can resist his overpowering evil. He inflicts the most terrible pain upon his slaves and leaves them begging for more. He takes the women he loves into his private world of tenderness and pain; but a violent death awaits those who incur his wrath.
