In Egypt, Giza, 1928, a colossal coverstone is uncovered, which houses a stone ring
underneath it. The expedition commissioner’s daughter takes an amulet inscribed with the wadjet of Ra from a work table
at the site. In the present day, Egyptologist Daniel Jackson is approached
at a symposium by an old woman wearing the Ra necklace and is offered the chance to translate Ancient Egyptian hieroglyphs
that may prove his theories that the pyramids weren't built in the 4th Dynasty. Curious, Daniel accepts before being given
tickets to an Air Force installation. Meanwhile, retired Air Force colonel
Jonathan “Jack” O’Neil as brought out of retirement to head the project. At
a U.S. military installation inside Creek Mountain, Colorado, Jackson meets the old woman, who introduces herself as Catherine
Langford. Daniel correctly translates the hieroglyphs on the coverstones, which read, "A million years into the sky is Ra,
Sun God. Sealed and buried for all time, his Stargate." O’Neil then arrives to take command of the project and declares
all information regarding it classified. Daniel makes an accidental breakthrough
after noticing that star constellations on a newspaper are identical to the symbols on the coverstone. Later at a meeting,
Daniel reveals his findings and theorizes that the constellations on the coverstones are coordinates for a location within
space, while the seventh symbol represents "a point of origin". The stone
ring, identified as the Stargate, is revealed to Daniel, identifies the seventh symbol after looking at the symbols on the
Stargate. The seven symbols are then entered into the Stargate, which opens a wormhole. A probe is sent through the Stargate
and is tracked to a location in the “Kalium Galaxy” on a planet on the other side of the universe. The probe sends
back images on the planet it is on before the wormhole disconnects. The images sent by the probe reveal that the world it
was sent to has an atmosphere similar to Earth and that the Stargate on that planet has a different set of symbols on it,
making a return to Earth impossible unless the symbols on the other Stargate are translated. Daniel convinces the military
to send a team through the Stargate and let him go with them, as he will be able to translate the symbols on the other Stargate.
O’Neil leads a team to go through the Stargate. Catherine gives Daniel
the necklace she picked up in 1928 as a good luck charm. The Stargate is reactivated and the team, including Daniel, goes
through it. On the other side, the team finds themselves inside a pyramid which they exit to reach outside. After Daniels
reveals he can’t dial home without the coordinates for Earth, O’Neil orders the team to set up base camp and returns
to the pyramid to assemble a hydrogen bomb. Outside, Daniel notices tracks and follows them back to a domesticated alien beast,
a Mastadge, only to get caught in its reins and dragged off to a nearby village where humans are mining, with some of the
team following. The team approaches the villagers, who assume them to be gods sent by Ra and bow before them. O’Neil
tries to offer friendship to a boy named Skaara, but in fear, the boy runs off to get his father Kasuf, the tribe’s
leader. The team is forced to stay in the city after a sandstorm hits it. At the base camp, the other members of the team
head into the pyramid for shelter. Daniel attempts to communicate with
the locals by writing, but discovers that this practice is forbidden. A young woman, Sha'uri, is presented to him as a gift.
Sha’uri shows Daniel a cave full of hieroglyphs after he attempts to communicate with her. Daniels learns that the language
of the people is Ancient Egyptian, which he can fluently understand due to his background. Meanwhile,
a huge pyramidal craft lands directly on top of the pyramid. The team members still inside the pyramid are attacked and captured
by an unknown entity. In the city, O’Neil locates Daniel, who manages
to translate the hieroglyphs. The hieroglyphs reveal that the Egyptian god Ra was actually an alien, the last of his kind,
who was attempting to extend his own life. Ra traveled to Earth and encountered humans, who he enslaved with his advanced
technology. Ra also used a young boy as a host body and appointed himself ruler of Earth. Humans were transported from Egypt,
on Earth, to the other planet using the Stargate, and used to mine the mineral on which all of Ra’s technology was based,
including the Stargate. The humans on Earth rebelled when they discovered Ra was not a god and buried the Stargate. Fearing
the same thing would happen on this planet, Ra outlawed reading and writing to prevent the humans there from learning the
truth. After explaining this to the others, the team locates a center stone similar to the coverstone on Earth that has symbols
from the other Stargate on it, with the seventh symbol eroded away. O’Neil then orders the team to return to the pyramid.
The team leaves the city the next day to return to the pyramid and Skaara and
his friends secretly follow them. Going back inside the pyramid, now housing the pyramidal craft on top of it, the team is
attacked by a creature modeled after the Egyptian god Horus. O’Neil notices that the bomb has disappeared. Suddenly,
nine rings descend from the ceiling and deposit two Horus creatures and an Anubis creature, which promptly capture O’Neil
and Daniel, who are taken into the pyramidal craft. O’Neil and Daniel
are escorted to the throne room, where they meet Ra, who reveals he has the hydrogen bomb. O’Neil attempts to disarm
the guards and kill Ra. Daniel is shot and killed in the resulting firefight. O’Neil relents when Ra uses his children
workers as a human shield. After his surrender, he is thrown into a dungeon with the captured team members. Daniel is regenerated
with the same sarcophagus Ra uses to revitalize his host body. Daniel then returns to the throne room, where Ra reveals that
he intends to send the bomb, with its destructive capability enhanced by the mineral, through the Stargate in retaliation
for the rebellion on Earth. Ra states that he will kill Daniel and everyone who has seen him unless Daniel kills the rest
of the team to show the people that he is their one true god. In the city,
Sha'uri reveals to her fellow people the translated hieroglyphs and the truth behind Ra and that they should not live as slaves
anymore. However, the people don’t believe her. The people in the
city gather before the pyramid craft to witness the execution of the people from Earth. Skarra signals to Daniel that he and
the rest of the locals have stolen weapons from the team. Daniel then shoots Ra while the locals fire into the air to create
a distraction. O’Neil, Daniel and the rest of the team flee Ra's ship and take shelter in a cave with the locals. Daniel
confronts O’Neil about the bomb and O’Neil reveals that he was given orders to destroy the Stargate if any threats
were found. Daniels wonders why O’Neil would be willing to throw his life away; O’Neil reveals that he watched
his son accidentally shoot himself with his gun several years ago. Daniel reveals Ra’s plan to send the bomb back to
Earth and O’Neil declares he’s going to stop it. Later, Ska'ara
draws a picture of the people's victory against Ra, which depicts three moons over a pyramid. Daniel realizes the picture
represents the seventh symbol needed to reactivate the Stargate. Daniel prepares some food at a campfire and is laughed at
by the locals, who mention that "husbands don't do this work." He realizes that Sha'rui, the young woman given to him, is
his wife. Sha'rui feels that she wasn't wanted, but Daniel proceeds to demonstrate to Sha'uri that he wants her very much.
The next day, Ra's guards search for the escapees by keeping an eye on the locals
coming in and out of the city. A guard locates Daniel and is shot dead by O’Neil with a staff weapon. Daniel reveals
the truth to the locals about their ‘gods’ and opens up the guard’s mask to reveal his face. The people
who doubted Sha’rui’s story now believe her. Later that day, the team infiltrates a mineral shipment caravan that
is to be delivered to Ra, to get inside the pyramid and escape with the bomb. The bomb is sent down to the Stargate so that
it will be sent through with the mineral when it arrives. After they reach
the pyramid, O’Neil, Daniel, Sha’rui and several locals rush into the pyramid and defeat the guards. O’Neil,
Daniel and Sha’rui make it to the Stargate, although Sha’rui is shot and killed. O’Neil sets the timer on
the bomb to seven minutes. Just then, the transporter rings activate and Daniel uses them to transport onto the ship with
Sha’rui’s body. The Anubis guard transports to the planet in Daniel’s place and fights O’Neil.
Daniel uses the sarcophagus on the ship to revive Sha’rui. The two of them
then attempt to beam down using the rings, although Ra attempts to stop them. On the planet, O’Neil uses the transport
ring on top of the Anubis guard’s head, crushing him, which transports Daniel and Sha’rui down to the planet.
The locals, lead by Kasuf, overpower Ra’s guards in the city. Ra decides to retreat and prepares his ship for takeoff.
Inside the pyramid, O’Neil discovers that the bomb cannot be turned off due to Ra’s tampering. O’Neil and
Daniel then decide to transport the bomb to Ra’s ship, which has now left orbit, which they do. Ra watches as the bomb
explodes, destroying the ship and himself. The people are now free, and the team is able to return to Earth. Daniel decides to remain on the planet with Sha'uri and help the locals build a new society.
O’Neil returns to Earth with the rest of the team, a changed man given a purpose and a new reason to live. Daniel gives
Jack Catherine's necklace and instructs him to tell her it did bring him luck. The film ends with O’Neil returning to
Earth through the Stargate.
