An exclusive peek into the high-octane world of rope access technicians.

When America's hardest to reach structures need repair, there are few people with the courage and expertise to handle the job. Enter elite rope access technician, Trask Bradbury.

This series follows Bradbury and his team as they cross the US to undertake nerve-shredding work on some of America's most impressive landmarks - everything from colossal dams and sweeping bridges to giant rollercoasters and towering statues. With just rope - and each other - for support, it's a remarkable world of bravery, skill and ingenuity that has rarely ever been documented.
