Stargate SG-1: The Other Side

SINOPSIS

After 3 'impact' events against the iris, the SGC is contacted by humans that are at war and under attack. They plead for help and SG1 visits them. They are technically advanced, living underground in bunkers with much of their population in stasis, protected by shields and remotely piloted aircraft, but all is not as it seems and Jackson asks questions that elicit disturbing answers.
