Recruited by the Air Force to translate hieroglyphs on a mysterious artifact, Egyptologist Dr. Daniel Jackson discovers the instructions to an alien Stargate, a portal to another planet. He joins a military team led by Colonel Jack O’Neil, and together they travel to a world populated by misplaced humans, the descendents of Earth’s own ancient Egyptians. The team manages to befriend the inhabitants with chocolate and good will, and Daniel even manages to become inadvertently betrothed to the young daughter of their leader. But they are still struggling to learn the language when confronted by a formidable enemy. The alien who enslaves the new world, encased inside a human host and surrounded by an entourage of powerful soldiers armed with energy weapons, arrives with show of force. He takes hostages, among them Daniel’s new wife, and blocks the newcomers from returning home through the Stargate. The ensuing battle quickly becomes a struggle to rescue both the new world and Earth.
