Yanji is a small town on the northern border of China. Haofeng (Liu Haoran), who came from Shanghai to attend a wedding, felt a little lost. By chance, he met Nana (Zhou Dongyu), a young tour guide who fascinated him. She introduced him to a chef friend Han Xiao (Qu Chuxiao), and the three of them soon formed a friendship because of a meal at Han Xiao's. This warm contact made them face their past and secrets, and their dormant desires slowly unraveled, just like the scenery and snow forests of Changbai Mountain.
