The Wall.

In the early 3000's, so much as changed. Genetically engineered babies were made, made to be beautiful and look pretty. This turned against them. People protested in the streets, and these designer babies were looked down on in society, picking up the nickname as the Dollies.
In these early times, two children, Teddy and Dot, meet and become great friends. Their mothers reluctantly let them play together, despite their differences, until one day, the government takes drastic action.
The riots created around the country had brought the weak government to their knees, and in a drastic measure, build a 100ft wall between the two societies. People can cross the wall when they please, but get a 'hostile' reception on the other side.
Years later, these two kids have grown up into adults. Dot being a beautiful brunette, living in crippling poverty on the 'Dollies' side of the wall, where as Teddy, lives in luxury with his big family. But when Teddy gets too confident and crosses the wall to get some cheap alcohol for his 18th, he gets a nasty shock, and he now needs to rely on his childhood sweetheart to survive.
