David Grann regales viewers with some of the amazing true stories surrounding the wreck of The Wager, a British ship that sank off the tip of South America in 1741. In his book, "The Wager," Grann uses rare primary source documents to reconstruct the harrowing experiences of the ship's castaways and shows how the aftermath of the saga is still relevant today. The book will be adapted into a film directed by Martin Scorsese, as was another of Grann's bestsellers, "Killers of the Flower Moon."
