In this visually stunning and captivating series, we join world record stand-up paddleboarder and veterinarian Cal Major on an epic 800-mile ocean adventure around Scotland’s wild, dramatic and unforgiving coastline. We explore our human connection to the sea through the people of Scotland whose lives are intertwined with the ocean, and learn about the vital role our ocean plays locally and globally in the climate and biodiversity crises. From Cal’s stand-up paddleboard, we meet the creatures that call the ocean home, from the tiniest starfish to the largest apex predators, and dive into the stunning underwater world to discover its hidden riches. Through Cal’s deeply emotional and heartfelt adventure, we are transported to the wild and stunning Scottish coastline, journey tirelessly through the wind, waves and weather, through exhaustion, elation and awe, and make some shocking discoveries along the way.
