Bela Lugosi stars in this movie about a crazy scientist who makes a large bat to have revenge against some people who ripped him off when he came up with a pretty great perfume for women. The bat is wonderful. It is very large and swoops down on several people to kill them. It makes great noises before killing people, too, sort of a woooh noise. This is one of those campy movies that you should not take seriously at all but will probably enjoy a lot, if you have an open mind to everything it has to offer in campy humor and action.
