Cai Sanshui is 25 years old and lives like a rag that has been repeatedly wrung out by fate: he grew up in Sanming, making a living by doing odd jobs and writing poetry. He is sensitive, has low self-esteem, and does not even dare to hope to be "loved". Grandma Cai Jianqiu left only one wish before her death - she wanted to see the stars in Tibet. So he ran all the way to Lhasa and accidentally set foot on National Highway 318.
On the day he anchored on the plateau, he picked up a backpacker named Ma Youshan: short-cut, mean smile, venomous and nosy, who broke into his world like the sun. After traveling together for a month, camping, getting lost, quarreling, and playing UNO, Sanshui realized that what he feared most was not loneliness, but being taken seriously. Then a lot of things happened on the journey that made him realize that what he picked up in 318 was not a person, but a family.
