Brain damaged and broke, Rocky finds himself back where he started on the streets of Philadelphia. Boxing still very much in his blood, Rocky takes in a protege, training him in the style that made him a champ (take a lickin' and keep on tickin'). However an unscrupulous promoter has designs on the young fighter and seeks to wrest the lad from under the former champ's wing. This eventually leads to a showdown between Rocky and the young boxer in a brutal streetfight. Supposedly the last "Rocky" film, it's clear the formula has run dry.
