With the discovery of The Fountain of Youth, which caused people to age slower and live longer, a world that became overpopulated drove the government to convince the citizens that through transfer pods you don't die; you just go on to your new life. With the help of her sister and best friend Lilly, they discover a secret underground colony called TOP (The Original People) just months before their planned government takeover. Using the clues left by their father and the help of super intelligent birds, the girls assist in the takeover while also uncovering even more government secrets.
