Plot:

At the monumental Grand Canyon Sky Walk, in front of more than one thousand onlookers, Criss is shackled and locked inside a confining solid crate except for holes to view his face and hands at all times. The crate is then hoisted over the edge of the canyon more than 4,200 feet above the Colorado River. Criss reveals his process of escape but if he does not succeed in time, he will fatally crash to the rocky depths below.
