This was a tv series that was canceled almost immediately. I think there was only one episode as a matter of fact. Here’s what I remember.
A doctor makes a formula that makes you stop aging. After everyone in the world has taken it, about half of the people who have taken it turn into mutant cave people. The remaining civilized population all have crystals in their chests. The color of the crystal determines who you’re allowed to make babies with. If you breed with someone of the wrong crystal color, you risk giving birth to a mutant cave person.
Anyone know what I’m talking about?
