Planet Capo is situated on the other side of the black hole. There was a war and after a chemical fallout, the humans were left with an altered DNA. They must get to Planet Earth because they believe that by combining their altered DNA with that of the Earthlings, it would revert to the way it had been. On the night before the official launch to Planet Earth, Martex Renver and his friends go on board the spacecraft for a tour. After a mishap Martex becomes the new Commander, and his friends the new crew and they are on their way to Planet Earth to find a cure for their altered DNA. Martex must first destroy a meteor as big as a bus that is about to collide with them. When they land on Earth, they discover a problem. They are much smaller in size than the Earthlings. Martex meets the American President's daughter, Angela Andrews. They fall in love, but their size difference makes it impossible to have a normal relationship. Can Martex get back to his planet in time with the cure to save his father from an early death?
