S1, E9: When a UFO hunter disappears near a small town in upstate New York, the Librarians arrive to investigate with strict instructions from Jenkins: "Whatever you think it is ...it is NOT UFOS". When Stone strikes up a friendship with the cute, sarcastic Town Historian, he discovers that the town has a secret past, a past linking it to one of the great mysteries of the 20th Century. The Librarians would ordinarily turn to Colonel Baird for guidance, but she's become one of the "abducted", and can't be found! Stone finds himself torn between helping the locals, with whom he feels a kinship, and risking an apocalypse brought on by a hidden faction within the town. Can he convince his fellow Librarians to help him, or will the loss of Colonel Baird throw them into disarray, and eventually destruction?
