Laurie Strode (uit de eerste twee Halloween delen) is nu de hoofdlerares aan een prestigieuze privéschool, waar haar 17-jarige zoon op zit. Op de 20e verjaardag van de gebeurtenissen in het eerste Halloween-deel begint Laurie nachtmerries te krijgen over haar slechte broer, Michael Myers.
Nee, helaas is Halloween H20: 20 Years Later nog niet beschikbaar op Netflix in Nederland.
