Eight-year-old Shen Nian'an has always believed that she can only grow up by struggling like a wild weed. On a snowy night, she happens upon a missing-person notice, and the girl in the photograph looks remarkably like her. Clinging to her last shred of hope, she calls the number printed on the notice. On the other end is Shen Yanchuan, who has been searching for his daughter for seven whole years. One phone call and a journey through a snowy night bring a response to a family bond that has been severed for years. From strangers to recognition, from cautious testing of the waters to protecting one another, Shen Nian'an finally understands that those who truly love you will cross through wind and snow to find you, giving your wandering heart a warm place to call home.
