Alien Highway

Chuck and the team investigate the recent sighting of a possible shape-shifter near Utah's Skinwalker Ranch.

Chuck receives a map from an informant leading to an alleged cache of recovered materials from the Roswell incident; he and his team go on the treasure hunt of lifetime to locate what could be the mother lode of all UFO discoveries.

After an informant relays a story about an alien that reportedly escaped from Area 51, Chuck and the team head to Tonopah, Nev., to investigate whether this creature still roams the area.

Mysterious animal deaths and UFO sightings bring Chuck to Colorado to search for an explanation; reports of the incidents are going unanswered by authorities, leading him to wonder if it's a government cover-up.

A rash of recent UFO sightings brings Chuck and the team to Missouri, the home of the 1973 Piedmont lights incident; armed with new evidence, they tackle the question of whether history is repeating itself.

A Missouri man who claims UFOs are stalking him reaches out to Chuck and the team for help; during the intense investigation, they uncover a dark secret which may explain why their client is experiencing so much UFO activity.
