De drie Ninja's storten zich in een nieuw avontuur dat begint in een pizzeria waar Jo, een indianenmeisje, wordt lastiggevallen. Jack HArding heeft Jo's vader ontvoerd om de leden van de indianenstam stil te krijgen, die tegen het storten van illegaal chemisch afval op hun land protesteren. Maar de Ninja's moeten daar een stokje voor steken.
Nee, helaas is 3 Ninjas Knuckle Up nog niet beschikbaar op Netflix in Nederland.
