Shaft is recruited to go undercover to break up a modern slavery ring where young Africans are lured to Paris to do chain-gang work.

Private detective John Shaft travels to Africa after being engaged by diplomat Emir Ramila to infiltrate a slavery ring being run by the cruel Vincent Amafi. Amafi is having Africans kidnapped and sent to Europe as slave laborers, and when Ramila tried to expose him, he killed his son. After Shaft has been tutored so that he can pass as an African, he goes to Ethiopia to allow himself to be kidnapped by Amafi's group. But a traitor in Ramila's organization betrays Shaft's identity. Although he is now in danger, Shaft continues to free slaves while avoiding a series of attempts on his life.
