When a film emerges documenting an Army platoon under UFO attack, the Generals send Hynek and Quinn in to investigate, where they find the soldiers not only suffer from physical effects of war, but psychological ones as well.

Hynek and Quinn follow General Harding to Roswell, New Mexico, where an anonymous townsperson has threatened to expose evidence to the world of an extraterrestrial crash-landing six years ago.

Hynek and Quinn nearly reach a potential culprit, which could take them to just where they need to be to discover the truth behind the famous Roswell incident.
