At the horse races, Luke gives his winnings to a homeless woman who strikes it rich and moves to Africa to open a center to train Pygmies how to be Jockeys.
Luke sails to Africa aboard a ship commanded by a beautiful Greek seductress bent on destroying the South African fishing fleet.
While diving for diamonds in Namibia, Luke gets smashed in the head and loses all memory and motor functions. He awakens to find himself in the middle of the modern African slave trade run by Forest First, an eco-extremist group determined to remove the Pygmies from their forest homes and enslave them.
Luke joins a group of freedom fighters in a desperate attempt to bring down Forest First, and save the Pygmies from slavery and annihilation.
