Black Powder (Michael Jai White) is a well-known Kung Fu master and civilian hero in the black area. His brother Jimmy was recently killed by a drug gang, and the powerful senator canceled the anti-drug plan, resulting in drug abuse in the neighborhood. Black Powder must destroy the drug gang for both public and private reasons, but his former CIA colleagues who participated in the Vietnam War with him warned him not to act rashly. How can this stop Black Powder? This strange man who is merciful and has special skills finds his partners "Bull Horns" and "Cream Corn", as well as a group of revolutionary fighters, to launch a fierce attack on any gang under the influence of the drug gang... They have killed from street gangs to Chinese Kung Fu gangs, and at the same time have mastered the extremely evil plan of the drug gang's behind-the-scenes figures to shrink black people's penises, and the planner of this plan clearly points to the President of the United States. So, how will the grudge between Black Powder and the President of the United States be resolved?
