vampire clan / 2002 movie

This fictional feature film is loosely based on a true story. A young girl, Jeni (Stacy Hogue), discovers the bodies of her parents in their home. The local police zero in on Jeni's sister, Heather (Kelly Kruger), who hangs out with a tightly knit group of Florida teenagers who believe that they are vampires. The gang's leader, Rod (Drew Fuller), uses quasi-satanic rituals to convince the others they have supernatural powers, and is thought to be the one behind the murders.
