As a young woman prepares to get married, she becomes consumed with demons from her past. To reconnect with who she was before the trauma, she and her new husband walk 500 kilometers on the Great Himalaya Trail to a significant place from her youth: Lake Tilicho, one of the highest lakes in the world. But when faced with treacherous terrain, snow storms, near-death accidents, resurfacing repressed memories, and seemingly insurmountable barriers, she realizes that maybe she wasn't supposed to go back.
