With their trust and love for each other, Cheng Che and Youyou started their journey in the snowy no-man's land in an RV.
Along the way, they once exited the no-man's land due to a foot injury. After re-entering, they encountered an avalanche, got lost in the fog, took the wrong road, and the RV leaked. Cheng Che fell ill after working all night...
Of course, they also saw beautiful scenery such as shooting stars, wild snow leopards, the ice crystal lakeside, golden mountains under the sun, and a chance encounter with the scientific expedition team dreaming of the Big Dipper.
This is their journey, and it is also an in-depth exploration and thinking about freedom, distance, life, and emotions in each of us.
