Het is dertig jaar geleden sinds de kwaadaardige tovenares Rita Repulsa uit haar gevangenis wist te ontsnappen en de wijze Zordon als antwoord daarop de Power Rangers vormde. De Rangers, inmiddels volwassen, komen wederom bijeen als Rita in een nieuwe gedaante terugkeert en één van hen doodt: Trini, de oorspronkelijke gele Ranger. Samen met de dochter van Trini trachten de resterende leden - Billy, Zack, Rocky en Katherine - hun oude aartsvijand te stoppen en de aarde te redden.
Ja! de film Mighty Morphin Power Rangers: Once & Always is nu beschikbaar om te kijken op Netflix in Nederland.
