In 2018, a shocking event made headlines around the world: a young American missionary, John Chau, was killed by arrows while attempting to contact one of the world’s most isolated Indigenous peoples on remote North Sentinel Island. From Emmy-winning directors Amanda McBaine & Jesse Moss with Oscar-winning producer Simon Chinn & Emmy-winning producer Jonathan Chinn of Lightbox, comes National Geographic Documentary Films' The Mission, which uncovers the gripping story beyond the headlines. Through exclusive interviews and with unprecedented access to Chau’s secret plans, personal diaries, and video archives, The Mission examines the mythology of exploration that inspired him, the evangelical community that supported his quest, and reveals his own father’s heartbreak as Chau's youthful thirst for adventure became a fatal obsession.
