From the pro­duc­ers of Ancient Aliens and The Curse of Oak Island comes The UnX­plained, a one-hour, non-fic­tion series that explores the world’s most fas­ci­nat­ing, strange and inex­plic­a­ble mys­ter­ies. Host­ed and exec­u­tive pro­duced by Gold­en Globe and Emmy Award-win­ning actor William Shat­ner (Star Trek, Boston Legal) each episode will fea­ture com­pelling con­tri­bu­tions from sci­en­tists, his­to­ri­ans, wit­ness­es and expe­ri­encers-each seek­ing to shed light on how the seem­ing­ly impos­si­ble actu­al­ly can happen.

The HISTORY® Chan­nel, a divi­sion of A+E Net­works, is the pre­mier des­ti­na­tion for his­tor­i­cal sto­ry­telling. From best-in-class doc­u­men­tary events, to a sig­na­ture slate of indus­try lead­ing non­fic­tion series and pre­mi­um fact-based script­ed pro­gram­ming, The HISTORY® Chan­nel serves as the most trust­wor­thy source of infor­ma­tion­al enter­tain­ment in media. The HISTORY® chan­nel has been named the #1 U.S. TV net­work in buzz for sev­en con­sec­u­tive years by YouGov BrandIn­dex, and a top favorite TV net­work by Beta Research Cor­po­ra­tion.
