In order to escape from her mother's remarried family, 16-year-old Yiwei ran cargo with her father, who was a Shenzhen-Hong Kong freight driver, from time to time, hoping to earn money to rent an apartment outside with her father. In the process, she met a Vietnamese girl named Ling, and became close friends. Suddenly, one day, Ling disappeared with all the money that Yiwei had saved up. Just as Yiwei was losing her mind, she found Ling in her father's truck accidentally. At that moment, Yiwei realized that she was always being a pawn in the scam about smuggling.
