A film following Huw Jack Brassington as he attempts to run the notorious Paddy Buckley Round - a 100 km fell running challenge. Those who are brave enough to take on the round must climb 8,000 meters over 47 of Wales' highest mountains in just 24 hours. But when a massive summer storm hits Snowdonia, Huw must push the boundaries of his strength, endurance, and determination further than he's ever done before.
