High above the Italian Alps, Emmy-nominated actor Jesse Tyler Ferguson joins Bear Grylls for a 48 hour adventure of a lifetime. As the two negotiate the Croda Dei Toni, a snowy peak referred to as the "Mountain of Thunders," they will make a 6,000 foot descent along steep sheer cliffs and sharp ridges, build a snow cave for shelter and eventually rappel a frozen waterfall to their extraction point. Along the way, Ferguson shares some personal insight about his sudden rise to fame with "Modern Family," his fight for marriage equality and the challenges he faced growing up.
