Two musicians working for Umbra use their music to summon a Magnetic Monster on Earth. The Orbots must unite to stop it before it destroys the planet.

Earth: the 23rd century. A time of robots and aliens. And of destruction and terror! Can the Galactic Patrol, defender of the United Planets, stop the evil computer Umbra? You bet they can!
