Casting Shadows

Earth's population has skyrocketed in the past 200 years. One day, people are assigned a lottery number and advised to tune into a specially televised program as the subject is of national importance. It's announced that 300 million lucky 'winners' have been randomly selected to inhabit a new dwelling area to help solve the issue of overcrowding.
Almost overnight, swarms of military troops (Community Compliance Officers - CCO's) come in and forcibly remove chosen citizens from their homes. Resistance is futile.
In a few short years, the goal of the relocation effort is finally made clear. All resources are being allocated to the Towers of civilization.
Citizens below are left to starve and wither away. Crops no longer grow due to massive blockage of sunlight from three gargantuan Towers made to house and pamper a select few. Anarchist resistance movements are formed on the ground level. People form new families and connections with others to ensure better chances of survival. Three people's lives will intertwine and be forever changed. The better question is-who will get out alive?
