Jones is just really a secret agent who has gone into semi-retirement, focusing rather on teaching the martial arts. The karate school is run by a kindly old coot named Pops,played by Scatman Crothers. His gambling debts bring the thug, Pinkydown on him. To make things even worse, Pinky is hired by a few white thugs who would like to get hold of the property Pops' school conveys they could build a retail complex. After things get heavy, Black Belt Jones leaps into actions. Just he's not alone. Pops' daughter, Sidney, shows up to give a hand, demonstrating herself just as powerful and nimble a British performer as Jones.
