In a world in which the capital has cut off and isolated a single town from the entire world, one girl manages to break through the cage of isolated inhumanity and seek a return to normality. While everyone was brainwashed and nobody has the ability to remember their own past, Sera begins to remember; the pain, the suffer, the inhumanity of the capital. Sera's, better known as 598's screams are never heard, but always muffled and strength just might be the one thing that can break her out of the capitals cage. Sera's determination starts the sparks that will inspire a single guard and together both people from two different and separate worlds will work together to reestablish humanity in society.
