It would be hard to believe if it hadn't actually happened. The longest law-enforcement chase in nautical history, spanning 110 days and 10,000 miles, featured a bunch of vigilantes pursuing Interpol's most wanted illegal fishing ship. Slaloming around icebergs in a deadly glacier field, cutting through a category 5 storm, this chase only ended when one of the ships sank. To discuss why illegal fishing is so rampant and unchecked, this episode takes us from the capture of the world's most notorious scofflaw vessel in African waters to the seas off the coast of North Korea, where we discover the planet's largest illegal fishing fleet.
