Alien Invasion

All his life, the professor worked on a secret project that nobody knew about except his little son, Albert, who lives with him. He had a grand plan: to end mankind's lonely, secluded life in the universe once and for all, and open the door to new worlds, new galaxies, new technologies. The Stargate, his great invention, should open a wormhole to worlds inhabited by peaceful, benevolent aliens who have the technology to cure every known disease that mankind has long battled. But something went wrong! Evil aliens found out about the star gate and are on their way to earth. These have only one thing in mind: conquer the planet and enslave or kill everything that lives on it. The Stargate MUST be closed immediately!
