Plot Summary

Dr Jekyll embarks on an obsessive quest to find an elixir of life. He thinks he's found it in a potion derived from female hormones which he obtains from bodies in a nearby morgue. When that supply dries up, he employs body snatchers Burke and Hare – who eventually turn to murder – to find the body parts he needs. But his experiment is only a partial success – when he drinks his elixir, he transforms into a young woman who passes herself off as the widowed Mrs Hyde. When Burke and Hare are attacked by an angry mob, Mrs Hyde begins to murder in Whitechapel, giving rise the the Jack the Ripper legend…

“It can presumably be taken for granted that horror fans will not carp at the liberties taken with the historical facts of how Burke and Hare got their deserts, nor quibble at Dr Jekyll's knowledge of hormones. But these idiosyncrasies draw attention to the general looseness of a plot that leans heavily on coincidental encounters. The basic idea is very ingenious, particularly in view if the present vogue for injecting horror films with sex, but has the built-in drawback of lessening the visual impact of Jekyll's transmogrification into Hyde. This leaves only the murders to chill the blood and these are carried out with an efficient sameness that scarcely warrants a shudder.” – from a review by Marjorie Bilbow
