The Mafia learns that a new civic center will be built, and they buy all of the land for the site of the building—all except for one place: a karate school owned by Pop Byrd (Scatman Crothers). They arrange to have Pinky (Malik Carter) come by to force Pop to sell his land, but he is killed by them. It's up to the karate school's students to get the hero, Black Belt Jones (Jim Kelly), for help. Sydney (Gloria Hendry), the daughter of the late Pop Byrd, won't sell the building. Because both of them are martial arts experts, they join forces to "clobber the mob". The Main musical theme was performed by the funk guitarist Dennis Coffey.
This movie was done at the height of the "Blaxploitation" era. Michael Jai White has made a movie in honor of this one called "Black Dynamite." These movies represent the struggle of black actors to find movie roles in which they played the hero.
