A pilot for a sci-fi TV show. The show takes place in an apocalyptic future where there was a drug created that could grant eternal youth. Everyone took the drug, and things went fine... for a while. Eventually the majority of the population mutated into violent primitive beasts. Those who did not suffer the ill-effects of the drug, as well as those who refused to take it, lived in isolated cities around the world, such as Island City, which featured Star Trek-esquire shields.
Every citizen bore a crystal implant below their neck. This implant would glow a specific color. One could only mate with others who are of the same color to prevent mutated offspring. It was very interesting, the clothes were all designed around the crystal, and the nightclubs were divided into color-specific sections. "Hey baby, I see that you too have a blue crystal..."
If memory serves, the show focused around the leadership of the city, and more so on the leadership of of the police force of Island City.
It was a very cliché cast:
You had the leader guy The 2nd in command An adolescent male A mutant who was sane on the police force, who could never mate and who was also persecuted A tough guy and a few hot chicks
The teenage boy was the son of the hot chick, who was married to a very old man, who is old because he refused the treatment.
All in all, there was, and IMO still is, a lot of potential for the story.
