At Dawn They Sleep (2000)

Stephen and Ian are ruthless drug lords who are in the middle of a war with their rival Billy Rae Douglas. One night Stephen and Ian escort two girls home with them, who actually seem to be stranger than they are. The next morning they wake up and the girls are gone, and Stephen and Ian are not feeling so well and soon find out their lives have been changed forever. They find out that the girls were Angels that infected them with a vampire type virus. In exchange for immortality, Stephen and Ian along with the other hordes of Vampires, are to kill off the human race so that the Angels can take back what should have been theirs. The Vampires begin their slaughter until the Demon world steps in to put an end to the Angel's plans, for the Demons are satisfied with the way the three worlds co-exists.
