During an expedition in the Amazon in 1906, British explorer Percy Fawcett (Charlie Hunnam) grows obsessed with finding a lost city that could be the key to understanding the origins of human civilization. Over the next two decades, he returns to the Amazon multiple times in the hope of unearthing its location. Tom Holland, Robert Pattinson, Sienna Miller, and Angus MacFadyen co-star in this adaptation of David Grann's 2009 nonfiction novel, which was directed by James Gray (The Immigrant, We Own the Night).
