In 1968 visionary environmentalists Yvon Chouinard and Doug Tompkins undertook a legendary expedition to Patagonia. Almost 40 years later, adventurer Jeff Johnsen retraces their journey.

Following in the footsteps of his idols, Johnsen hopes to rediscover the same pristine natural landscapes. Instead, Johnsen encounters environmental pollution on a threatening scale. Yves Chouinard's and Doug Tompkins' expedition profoundly shaped their ecological thinking and influenced their activism. Their journey inspired the creation of one the world's largest and most successful national park projects in Patagonia.
