Black Belt Jones is a 1974 American blaxploitation martial arts film directed by Robert Clouse and starring Jim Kelly and Gloria Hendry.
The Mafia have learned of the construction of a new civic center, and have bought up all the land at the intended building site except for a karate dojo owned by "Pop" Byrd (Scatman Crothers), who refuses to give up his property.
The Don contacts an indebted drug dealer named "Pinky", who had laundered $250,000 from the Mafia that he'd subsequently loaned to Pop Byrd in-order to get the dojo built.
"Black Belt" Jones (Jim Kelly), an expert martial artist and hand-for-hire, is contacted by his old friend Pop to help protect the dojo.
Though Pinky intends to offer Pop to trade the building in exchange for clearing their mutual debt to the Don, he accidentally kills him during an intimidation attempt.
