Laurie Strode (Jamie Lee Curtis), now under a new name, has built herself a respectable life as a school mistress. But when her brother, the Shape Michael Myers, tracks her down and threatens her family, Laurie shows that age has not mellowed her.

Follows HALLOWEEN (1978) and its sequel HALLOWEEN 2 (1981) but made redundant by HALLOWEEN (2018).
There was also HALLOWEEN RESURRECTION which followed H2O but it wasn't any good.
HALLOWEEN H20 is very 90s but has JLC's mother, Janet "PSYCHO" Lee playing Laurie's mother.
