After separating from his wife, Leonard Parker (Cosby) quit the spy business and became a restaurateur. His wife refuses to speak with him, and his daughter, who changes her career more often than her clothes, has begun dating a man old enough to be Leonard's father! On top of it all, the government has asked him to come back and save the world again.
Unfortunately the movie Leonard Part 6 is not yet available on HBO Max.
