Part of BBC America Reveals.

As seen on NBC's Today Show, BBC AMERICA premieres the heart-stopping documentary The Human Spider, which follows the planet's most daring free-climber, Alain Robert, as he attempts to scale, completely unaided, some of the tallest buildings in the world. Robert's latest conquest, the New York Times building, joins a tall list of iconic towers that he has conquered including the Taipei 101, the Eiffel Tower, and the Empire State Building.

This visually stunning and adrenalin-fueled documentary constructs a fascinating psychological profile of Robert and gains exclusive access to his quest to "free-climb" more of the world's most iconic landmarks including a selection of the tallest structures in Shanghai, Berlin, Moscow, Lisbon, and London.
