Bear takes Marvel superstar Anthony Mackie to the highest peaks of the Italian Dolomite mountains for an adventure he'll never forget. Braving freezing conditions, they travel in the footsteps of World War 1 soldiers, conquer sheer cliffs and hunt snow rats. Along the way, Anthony opens up about his career, the passing of his dad and the pressures of being a father in his own right. But being a bona fide superhero doesn't prepare Anthony for their final ascent up an icy waterfall, where even the smallest slip could lead to disaster.
