Jiang Yuanzhou, a lonely girl who grew up in an orphanage, transferred to a strange city with all her secrets. Li Xiao, a seemingly unruly junior high school student, struggles to survive between his alcoholic and violent father and his mother who is struggling to make a living. When the two met in a damp alley, a mint candy became a tiny light connecting them.
As the friendship deepens, the pain they each bear gradually emerges - the shadow of Jiang Yuanzhou's childhood being abducted and the lingering cloud of violence in Li Xiao's family. On the eve of the high school entrance examination, a legitimate defense turned into a murder case. When the director of the welfare home suddenly revealed the truth about their blood relationship, the two girls had to embark on a road of escape amidst rumors and oppression. They passed through the neon lights of the city and the darkness of the mountains, and finally understood that some sufferings are like the boundless river, but the sincere bond will eventually become an unsinkable boat.
