Two years ago, Bob Riley abandoned his wife, Cathy, days before their planned three-week hike on the John Muir Trail. She went alone and lost her life on the trail. The only way Bob can live with the guilt is to help her finish her long bucket list of hikes. Cathy longed to stay at the historic Sperry Chalet in Glacier National Park, but her previous plans unraveled when it burned to the ground in 2017. Though Bob could not secure a prized reservation at the rebuilt chalet, he visits the mountain retreat on a four-day backpacking trip down the Gunsight Pass Trail. Follow Bob, a lonely widow, enthusiastic newlyweds, and a dysfunctional family as they face challenges posed by the trail and a few misguided hikers. Will trail magic help Bob to meet Cathy's lofty expectations? Will any of Bob's trail friends become more than friends? How many lives will Bob change by just doing the right thing? Will Cathy's hiking mascot, Marty, help keep Bob's memories of her fresh? Join the adventure from the comfort of your home as you relive your own hike or plan your next adventure.
