Gino and Fred begin in Austria's Zillertal Alps, where melting glaciers highlight climate change; exploring meat's impact, they try vegetarianism and discover innovative culinary alternatives in Vienna.

In their final journey, Gino and Fred head to Croatia, shocked by over-tourism in Dubrovnik; they explore Mali Ston's shellfish before road-testing Croatia's answer to sustainable travel with agro-tourism, then cross the Adriatic for an adventure.
