A scientist develops a formula to reverse the aging process. He wants to use it on himself and his sister-in-law, leaving his wife out of the picture. The sister-in-law has serious moral reservations, but longs to be young again.

Norman Rose plays a pretty creepy "scientist" here. His name is Jim and at one point in Act 3 a character says "Jim - no" to him. Sounds eerily like "Jim Jones". And the scene involves drinking a liquid.

This may be a spoiler. Nitpicking here. The scientist experimenting on the old dog made the dog 1 year old again with his formula. Now off the top of my head dogs have a life span of 10 or 12 years. I didn't catch how old the people were but if the scientist having taken the formula became 25 years old and then he says he would need to take the formula again in 40 years, we can assume the old people are 65. Here's the rub, if the formula takes off 40 years, then the 12 year old dog would revert to 28 years before it was born. Not a 1 year old dog. If the dog grew just 11 years younger, so should the people. They should be 54, not 25.


No, because the dog would get a different dosage than a human would. Also, and "dog years" are measured differently than human years.


A one year old dog is equal to a young person in their twenties, so actually the story was correct.


In fact, I just looked it up and a dog's first year of life is only equal to 15 years of a human's life, lol! :D Year 2 of a dog's life would be equal to a human about 23 or 24-ish. Of course, maybe he wanted a "teenage" dog, so he gave the dog extra formula, lol! In any case, you can't measure dog years, based on human years.


Dog years has nothing to do with it. It reverses the aging that is done in a span of time, that's all.

For a moment in Act III I thought that the scientist decided that he loved his wife after all, but then was proven wrong almost immediately (for those who have listened, I think you'll know what I'm talking about). This was a fairly decent listen of what obsession can do to people (at least, that's one of my takes on it).


Scientist Nathan Hardy’s obsession to keep his human rejuvenation formula a secret terrifies his wife Beth, who summons her sister, Jessica Stone, for help. Hardy reacts by telling Jessica he can guarantee her renewed youth if she will marry him, and he becomes outraged when Jessica rejects him and tells Beth about his proposal. The deranged scientist then makes plans to poison Jessica, but his diabolical scheme seems jinxed by an unexpected murder.
