A man is bitten by a bat in a cave. He begins to exhibit strange symptoms. People start to die in horrible ways.
Despite the obsession with bats and blood, this is more of a werewolf story than a vampire story. On the other hand, it's hard to tell; one of things this movie fails to do is set any ground rules on the whys and wherefores on being a werebat, so it's hard to tell. It's also marred by an overly leisurely pace, too many close-ups of bats (who apparently shriek like hawks) and of eyes. Some odd touches here and there do help a little, but not enough. The seventies-style ending is odd, inconclusive, and not really very satisfying. All in all, this one is pretty forgettable.
