An oddly shaped planet complete with giant life-forms appears in the 999's path. Though they have the desire, the planet lacks the desire to move and the 999, unable to escape, sinks into the planet. In order to rescue the 999, the Galaxy Railways Administration decides to send out oscillation waves to destroy the planet. When that is supposed to happen, a transparent woman lands in a space ship.
