Synopsis: Thousands of monstrous bats fill the night sky of a terrified village, while residents are murdered in their beds, drained of all their blood. As the killings increase, rumors of a vampire in their midst sends the townspeople into a frenzy of panic, as even the most respected scientist of the community seems convinced by the evidence. Only one investigator refuses to believe the superstitious tales and argues that a maniac must be at the root of the killings. A mob gathers to hunt down the suspected vampire and drive a stake through his heart, yet the exorcism fails to end the horrific slayings.
