After years of trying to decipher codes on an ancient portal found in the Egyptian desert, the government sends and archeologist and a military team through it. The portal transports them to a primitive society where they come face to face with their past.

A very interesting and thought provoking story. The effects are not abundant, but they work well. Nice script that blends heavy theory with heavy action. An intelligent sci-fi adventure that may become a favorite. Spawned the SG-1 television series..

Directed by Roland Emmerich.
