"Sometimes all it takes to save someone is to give them a reason to delay their decision."
Su Qing stood by the Namtso Lake, surrounded by snow-capped mountains, and the lake was as blue as a mirror, but she just wanted to end her life. Years of depression, workplace betrayal and the death of family members have pushed her to the edge, and this trip to Tibet is her farewell to the world.
At the decisive moment, Chen Yu appeared - a former rescue team member who ran a small inn in Tibetan areas, and his own soul was also trapped in the cage of the past. He saw her intention, but did not reveal it. He only kept her on the grounds of "helping me take care of the inn for a few days."
On a plateau at an altitude of 4,718 meters, two injured souls began an unexpected coexistence. By participating in simple inn work, contacting simple Tibetans, and experiencing the daily life of pilgrimage, Su Qing gradually felt the pulse of life again next to the purest lake in the world. In the process of helping her, Chen Yu also faced his past of escaping due to failed rescue.
When a snowstorm comes, the two must work together to cross the extreme environment in order to save a sick child. During this arduous journey, they finally completed each other's redemption and found the courage to move on.
