A sixteen year old teenager Haoran escapes from his home when his parents decide to live abroad. Instead, he lives with his classmate, Luyang, at the shabby city village in downtown Shenzhen that is bound to be reconstructed. At an exhibition held here, he cannot take his eyes off a photo of the back of a "beer girl". During Haoran's stay, the maturity of Luyang's sister, Shiyan, makes Haoran's heart flutter. However, in a wandering caused by his insomnia, Haoran accidentally discovers that the "beer girl" is Shiyun. Out of a desire to protect and possess her, Luyang goes to the food stall every night and saves her from people who try to make Shiyun drunk regardless of her own will.
