Two spaceships are travelling home when one crashes on a planet. The other one returns to rescue them but 3 months on the rescue ship is 18 years for those on the planet due to time dilation. Once they land on the planet they have to battle the planets inhabitants and meet the descedant of the survivors. This is a poor low budget sci-fi film that deals with race relations as on the ship there are two races, the dominant white race and the subservient asian type race.
