Vampire Clan

Five friends welcome real life vampirism into their lives. They cut their own wrists and let their friends drink from them. Rod, the leader, and a very psychotic young guy, ends up killing Heathers parents and stealing their car to go on a crazy raod trip. His behaviour begins to frighten his friends, though they went along with it at first. All end up in prison except Heather.
