A famous jazz trumpeter finds himself unable to cope with the problems of everyday life.

J. T. Gamble, a shy, withdrawn Harlem youngster, shows compassion and responsibility when he takes on the care of an old, one-eyed, badly injured alley cat days before Christmas and secretly nurses it back to health.

After he retires from the police force, a veteran cop is framed for robbery but his friends, a rookie and three ex-cops, come to his rescue.

How does retired cop Joshua Burke (James Earl Jones) get two career criminals, Manny Durrell (Sidney Poitier) and Dave Anderson (Bill Cosby), to follow the straight and narrow? Con them into helping juvenile delinquents turn over a new leaf. But how? Burke has never been able to nail the duo, but he uses what he knows of their seedy past to blackmail them into volunteering.

Jack Spade returns from the army in his old ghetto neighbourhood when his brother, June Bug, dies. Jack declares war on Mr. Big, powerful local crimelord. His army is led by John Slade, his childhood idol who used to fight bad guys in the 70s.
