As ancient Transylvania struggles into modern times, old myths and superstitions blur with reality. Two American students, Michelle and Lillian, join their Romanian friend Mara in the Carpathian Mountains to study the legends of vampires. While the three innocents explore the mysterious village culture and rituals, a suppressed evil rises again and casts its shadow upon the land. Unknowingly snared in a centuries-old family feud, the girls fall into the clutches of Radu: a diabolical vampire prince whose madness and bloodlust know no bounds. To claim his birthright - the ancient Bloodstone - Radu kills his father and hunts his noble half brother Stefan. With Stefan's help, the girls fight for their lives against Radu and his minions - the Subspecies - an army of hellish creatures born of his own flesh. Will they survive to see the sunrise or will Radu curse them to eternal night?
