The logical thing, the sane thing, is to stay on land. But they paddle out. Why do these big wave surfers risk their lives to ride these mountain-sized waves? The answer is overcoming fear. "Ground Swell: The Other Side of Fear" is an in-depth look at the 2021-22 big wave season through the eyes of Nic Von Rupp, Kai Lenny, Matt Bromley, Torrey Meister and pioneering female surfer Bianca Valenti, along with a special appearance by Vini dos Santos and maybe the 100-foot wave. They all push past their fear and find out what is on the other side as they tackle monstrous waves in locations from Nazare in Portugal, Jaws and Pipeline in Hawaii and Mavericks in Northern California.
