Just three months after his wife's death to breast cancer, Jon packs up his infant son, Myles, and they set off on a six-week "Healing Tour" through Canada and the United States. Their journey, set to the soundtrack of the music Jon loves, sees them negotiating rolling mid-western hills, exploring a cave, losing confidence in the prairies, and finding it again in the desert states. As Jon starts to learn to balance his sorrow with the joy of new fatherhood, a sobering episode in the Rockies compels him to question what his life might have looked like had his wife survived. Part travel book, part love story, Immortal Highway explores the nature of love, family, and grief in incredible times.
