In The Sign Of The Virgin
The setting - a private boarding school for delinquent girls.
The board of Director's have realized that the planet Venus will be aligned perfectly for all sorts of risque behavior and it must be kept in check. They have come up with a powder that when added to water will curb all erotic desires so it must be administered to all of the girls at once by Professor Armand (Ole Soltoft).
Meanwhile Professor Bomwitz (Bent Warburg) has come up with a powder that when added to water becomes the strongest aphrodisiac known to man!
The two end up in the same town, bump into one another and accidentally exchange brief cases containing the powders.
Professor Bomwitz gives the girls their powdered water and empties the rest into the town reservoir causing sexual chaos and mayhem in the school and the entire town! Everyone ends up at the local brothel run by Madame Gine.
