Being the last country that hasn't been obliterated by missiles, Erillinen has separated its people into sectors based on what you value to keep the peace. When you turn 16, you depart from your sector, your family, and your friends by staying in a clinic and taking a series of tests and examinations to figure out what you value. It's been 100 years since Erillinen has separated its people. 5 individuals from different sectors meet at the clinic and find themselves doing something they never thought they do.
