Diep in de jungle hoort een kleine olifant plots een stem uit een klein stofdeeltje. Het blijkt een minuscule planeet te zijn waar de stad Who-Ville op gelegen is. De Who's geven Horton de opdracht hun planeet te beschermen met behulp van zijn vrienden. Naar het verhaal van Dr. Seuss.
Nee, helaas is Horton nog niet beschikbaar op Netflix in Nederland.
