影片根据泰·加涅发表的的文章《高处：雪地里的脚印引发了一场温情救援》(High Places: Footprints i n the Snow Lead to an Emotional Rescue，暂译)改编，讲述了母亲、护士兼登山爱好者帕姆·贝尔斯的故事，当她独自跋涉华盛顿山，被暴风雪困住时，她遇到了陌生的登山者并为其展开了一场大胆的营救。
The story is said to follow a pair of loner college undergrads, Jack and Montgomery, who order a take-out pie, but accidentally take a homemade drug that turns a two-floor journey downstairs into a “mind-bendingly transformative quest.”
On the verge of losing everything, veteran sprinter Gu Young is getting one last opportunity at redemption, including a chance to re-kindle the love of his life.
