While the plots and characters are unrelated, House II involves a storyline centered around a new mansion with a supernatural connection.

In the film, a duo of Yuppies settle in an old family mansion, and learn of the existence of a crystal skull owned by a recent ancestor of one of them.

They are soon joined by Jesse's goofy friend Charlie Coriell, who brought along his diva girlfriend Lana, in the hopes of being discovered by Kate, who works for a record company.

While going through old things in the basement, Jesse finds a picture of his great-great-grandfather (and namesake) in front of an Aztec temple holding a crystal skull with sapphires in the eyes.

In the background is a man Jesse learns is Slim Reeser, a former partner of his great-great-grandfather turned bitter enemy after a disagreement over who would get to keep the skull.

Jesse and Charlie take the cowboy zombie, nicknamed "Gramps", back to the house, where he is horrified to learn that the skull has not rejuvenated his body as he had hoped.

While seemingly a buffoon, he pulls a short sword from his tool case and leads the boys through "one of those time-portal things...you see these all the time in these old houses."

Jesse jumps through a window into the Old West, and eventually succeeds in killing Slim by blasting off his head with a rifle.
