Sequel to Cotton Comes to Harlem. Another bad influence is hitting Harlem and Gravedigger and Coffin Ed are the two cops who will stop it. Charleston Blue was a prohibition era black gangster, dead 4 decades. When he seems to have reappeared, once again slitting throats with his Blue straight edge razors, the two cops begin a complicated search for some answers.
