At the turn of the century, humanity has reached a technological high-mark with the creation of the G-Reaction, an advanced engine capable of extraordinary speeds. During the unveiling of a new train utilizing the G-Reaction system, the train and its technology disappear in a flash of beautiful light. Witnessing the disappearing act are Billy, Penny and Lotta. It isn’t long until the three teens discover that similar disappearances have been occurring across the globe, and an invasion looms on the horizon. With invasion imminent, the world’s greatest minds have joined forces to form the Labyrinth Alliance, and Billy, Penny and Lotta are its newest “volunteers.” Together the trio will help to pilot the Sky Knight, the only fighter plane capable of defending Earth from destruction.
