Fire in the Sky (S03E13)

In 1398 A.D. Pacific Northwest, Sydney is approached by businessman Bobby Green, who asks her to investigate a mysterious piece of metal discovered at a dig site in Washington State. Upon arrival, she and Nigel encounter hostility from the local sheriff, Dark Feather, and soon realize they are being pursued by government agents. As they evade capture, Dark Feather reveals his support for their investigation, leading them to a location filled with ancient tribal artifacts. Among these, they find markings that match the metal, which Sydney and Green suspect originated from an alien spacecraft that visited the tribe long ago. Green, claiming to be an alien abductee, hopes this evidence will validate his experience. Just as Major Hillhurst and his agents confront them at the cave, Dark Feather's deputies arrive to help. However, back in Sydney's office, chaos ensues as the metal relic is violently taken.
