In 1976, a drifting star named Gorath is discovered to be on a collision course with Earth. Although it is smaller than Earth, its enormous mass is enough to destroy the planet totally. A mission sent to observe Gorath is destroyed after the ship is drawn into the star, with a later mission barely escaping the same fate. However, Astronaut Tatsuma Kanai is left in a catatonic state due to his near death experience. Unable to destroy the invading star, Earth's scientists undertake a desperate plan to build giant rockets at the South Pole to move the planet out of Gorath's path before it is too late.
