In the shadow of Scotland's 3,000 abandoned castles, a team of world-class strongmen and explorers confront the heavy burdens of the past. Beyond the ruins of Buchanan Castle, where Nazi history and nature collide, lies a deeper story of brotherhood, autism, and the battle against addiction. Witness the transformation as physical limits are shattered and the internal strength required to lift a 100kg stone becomes a metaphor for reclaiming a life.
