 Egyptologist Daniel Jackson is brought to an underground military base where he decodes the symbols on Egyptian cover stones as star constellations. That allows a alien device known as the Stargate to be opened and a team led by Air Force Colonel Jack  O  Neil and Jackson to travel across the known universe to a distant planet. Arriving on the planet, they find a culture ruled by someone pretending to be the Egyptian sun god Ra. Soon, Ra captures the team and takes control of a nuclear weapon brought to the planet in case of the discovery of hostile aliens. Jackson and O Neil escape and must fight Ra and his army of warriors to save Earth from being destroyed by Ra.
