影片改编自美国作家谢莉尔·斯瑞德2012年的同名自传，讲述婚姻触礁，母亲去世，自己在绝望中生活多年之后，虽然毫无徒步经验，却独自一人踏上Pacific Crest Trail 远足之路，通过长途步行找回自我的故事。With the dissolution of her marriage and the death of her mother, Cheryl Strayed has lost all hope. After years of reckless, destructive behavior, she makes a rash decision. With absolutely no experience, driven only by sheer determination, Cheryl hikes more than a thousand miles of the Pacific Crest Trail, alone. Wild powerfully captures the terrors and pleasures of one young woman forging ahead against all odds on a journey that maddens, strengthen, and ultimately heals her.
