One of schlock horror-meister Roger Corman's favored actresses Susan Cabot stars as the title character, otherwise known as Janet, in this her last feature film for Corman. Janet is the aging but still glamorous head of a cosmetics firm who is looking for a way to improve her visage. Zinthrep (Michael Marks) has come up with yet another of those strange-sounding lotions or cremes designed to enrich the coffers of their manufacturers as the ladies surge to buy them. This time around, an ingredient taken from wasps is substituted for an original ingredient from bees. While the immediate effect is exciting, the subsequent effects are even more so because the miracle lotion turns Janet into a wasp, and a rather well-developed wasp at that. So the poor woman, suffering under the throes of unexpected wasphood, murders a few shocked employees in a rather gruesome manner. Not overly frightening, this film is a typical Roger Corman entry in the horror genre.
