Chris Emerson, a young former surfing pro and his younger sister Nicole move to Luna Bay, California, following the death of their parents, to live in a house owned by their aunt Jillian.

Chris showers with a girl named Lisa, and Shane gets Nicole alone, chats with her for a bit, and then tricks her into drinking his blood.

When Chris learns that Nicole has been with Shane, he angrily and protectively takes her home, where she begins to manifest vampiric strength and rage.

Chris interrupts her just before she can feed on 22-year-old Evan Monroe, a nice young man who has been courting her, and explains what is happening to her, and Nicole is surprised at what she almost did (because she believes herself to be a vegetarian).

Chris impales Erik with a large drill, and Edgar kills Kyle by making his head explode with a holy water balloon.
