Captain Kidd went to the gallows in 1701 without revealing where he stashed his loot, and legend has fed on the gap ever since. This episode of Myth Hunters follows treasure hunter Richard Knight, whose research points to a cache Kidd allegedly buried before his final voyage, and traces the clues through old maps, court records, and the pirate's own testimony given under interrogation. The film moves between historical reenactment, interviews with historians who lay out the documented facts of Kidd's privateering career and trial, and present-day expeditions to the islands and coastlines where the treasure is rumored to lie. It weighs the plausible history against the myth that grew up around it, showing how a working privateer commissioned to hunt pirates became, in the popular imagination, the pirate with the richest hidden fortune of them all. Whether or not Knight's search pays off, the episode is really an account of how a legend gets built and kept alive for three centuries.
