Sometimes They Come Back... Again is a 1996 film directed by Adam Grossman and starring Michael Gross, Alexis Arquette, and Hilary Swank.

Thirty years earlier, when Jon was a child, he witnessed the brutal murder of his older sister Lisa, who was stabbed to death in a cave by a greaser named Tony Reno and his two friends Vinnie and Sean, who were attempting a demonic ritual which Jon stopped by throwing an electrical wire into a puddle of bloody water they were standing in, killing all three of them.

Tony kills Steve with his lawnmower and uses his body parts to perform a ritual in order to bring Vinnie back.

While they're making out in the forest, Vinnie turns into a Demon and kills Maria in order to use her body parts to bring Sean back.

In the end, Jon reenacts the events of the murder of Lisa but saves Michelle and is able to use Father Roberts' ritual to banish Tony and his friends back to Hell.
