A highway construction site in southwest China——
Lin Nanfei, who just graduated from college, and a group of single men who are far away from their wives and children;
An ethnic village with rich ethnic customs and picturesque natural scenery;
The love and hatred between them, the hidden rules of officialdom, the missing children, the hardships of working life and the left-behind children——
The love of middle-aged people, the extramarital affair of a small boss——
And that girlfriend who has not yet graduated from college and is pregnant out of wedlock----
