An unearthly alien is sucked into Theskulis's plan, as well as the latest technology from the US military. Knightly must save the earth from being engulfed by a deadly, non-sentient alien who can destroy the atmosphere, while at the same time rescuing the volatile and yet helpless young girl in Theskulis's power.
