Naomi Arkoff, Robin Sydney, is tortured on a rack in the basement of a castle in Rome by her father Carver, Steve Kramer, for having a cell phone. He warns that next time the punishment won't be slow and painful. Naomi screams: >I can run faster than you!<
The next afternoon, Carver's wife Lisbeth, Samantha Light, questions what he did to Naomi. At lunch Carver tells his mentally retarded half brother Peter, Giacomo Gonnella, that the lamb they're eating is Sophia, for whom Peter has affection. Naomi cheers him up with her toy horse. Lisbeth takes a tray of food upstairs to her father and reads Edgar Allan Poe's From Childhood's Hour to him. She alerts him that his guardian angels are in the room, shown to be small creatures with big skulls.
Naomi tells Lisbeth she wants to get away to college and meet people and do exciting things. Lisbeth tries to dissuade her, telling about Naomi's grandmother who went to see the circus when Lisbeth was a baby and didn't come back. When Lisbeth was a teenager the circus returned and Lisbeth saw her mother in the circus performing acrobatics. Lisbeth finds an iPod under Naomi's pillow, but allows Naomi to keep it so long as her father doesn't know.
The next morning Kimi Evans, Kim Argetsinger, L.J., and Jenson arrive, Rane Jameson, Hollywood producers scouting locations. Carver tears up Kimi's business card telling Uncle Peter to escort them out. Naomi gathers up the card, sneaks a cell phone from a delivery boy, and invites the trio to dinner.
Having calmed her father over having guests, everyone settles for the meal when they hear something. The family explains it's "the protectors". The Romans buried the dead in catacombs and built the castle above to guard against grave robbers. The "Skull Heads" are born of witchcraft to protect the dead from violation.
Leaving after a tour of the castle, the film crew are revealed to actually be art thieves. The next morning, preparing to torture Naomi, Carver finds Peter trying to have sex with the maid Claudia, Lucia Stara. He beats Peter out of the room but has Claudia keep her pants down as he unzips himself. That night, Kimi, L.J. and Jensen sneak in and start stealing items.
Jensen finds and releases Naomi from the rack. As they're about to escape, they run into Carver and Lisbeth. Arguing over the right decision for Naomi, Lisbeth explains that Naomi is not only Carver and Lisbeth's daughter, but also their niece as Carver and Lisbeth are brother and sister. Naomi is a little retarded because she is inbred and confused over her identity. Suddenly, Lisbeth and Carver are shot by Kimi, who then forces Jensen and Naomi back into the basement.
Kimi has Naomi tie Jensen to the rack for betraying his partner, then presses a button causing the rack to run automatically and locks Naomi in a trap. L.J. and Kimi continue grabbing the valuables they had earmarked. The Skull Heads resurrect the bodies of Carver and Lisbeth as zombies and have them go after the thieves. Carver and Lisbeth corner L.J. and Kimi at the castle doors where they start eating off their faces, spraying blood all over the walls.
Peter releases Naomi and Jensen. Jensen follows Naomi upstairs to get her grandfather and is shocked to find he has been dead for quite some time. Suddenly, his body rises up and surprises Jensen, revealing one of the Skull Heads controlling his body. Jensen runs back downstairs, grabs Kimi's gun, shoots at Carver and Lisbeth and runs outside, shutting the doors behind him. Just as he thinks he is safe, a screaming Naomi opens the doors, grabs Jensen and pulls him back in, slamming the doors behind her.
