The year is 2032. An alien race called the Voltar now lives besides humans on Earth. The people have hope now since the Voltar have solved many of their issues. But there is more to this race then they think. Echo is an eighteen year old vigilante. She targets only Voltar's because of the murder of her sister. She knows the Voltar are evil. And she will stop at nothing until she cleanses her world.
"Why I do it? I suppose it’s a sick combination of revenge and feel that I was doing the world a favor. I don’t call myself a serial killer. That’s more of killing for no reason. I’m a vigilante."
