This documentary, written, produced and directed by Alex Winter, examines the case of Silk Road, the illegal drug trafficking site that lurked on the “Deep Web,” until the government shut down the site in 2013 and put its purported entrepreneur, Ross William Ulbricht, on trial. But as this documentary makes clear, nothing about the case, or the motives for the site, or even the identity of the Silk Road-running “Dread Pirate Roberts,” is as simple as it might appear. And yes, that pirate name is a knowing nod to The Princess Bride – one of dozens of interesting nuggets of information gleaned from this Epix documentary. Keanu Reeves narrates.
