On the day of Alice Wentworth’s wedding, mad scientist Dr. Lorenz sends the young bride a poisoned orchid, the scent of which places the young woman in a state of suspended animation. He then spirits her body away to the basement laboratory of his isolated mansion and extracts her bodily fluids to inject into his vain and aged wife in order to renew her youth and beauty. A young journalist, Patricia Hunter, investigates the case and discovers it involves an unusual orchid. She is directed to Lorenz, a known expert on orchids, and visits his mansion where she meets with a chilly reception. She is forced to spend the night when a storm breaks, and discovers the basement laboratory. In the morning, she hurries back to her newspaper offices. Hunter and her colleagues make an attempt to trap Lorenz but he outfoxes them, chloroforming Hunter and carrying her to his laboratory to use her bodily fluids upon his wife. During the injection procedure, Lorenz is stabbed by an angry servant woman who holds Lorenz responsible for her sons’ deaths. He strangles her then collapses and dies. The servant rallies weakly and stabs Lorenz‘s wife to death. The police arrive and Hunter is rescued.
