In this intimate portrayal of the lives of workers migrating away from home to the city in Vietnam, a young woman goes to the zoo to meet ex-boyfriends, and a married teacher has a secret relationship with a security guard.

Phuong, An, and Nhu are Vietnamese women in their early 20s. The three become illegal residents in Japan after escaping from their workplace as technical trainees. An contacts a broker to help them find work. The broker takes them to a fisherman's ice-covered hut where they can stay in exchange for labour. They are happy because, as well as finding a job, they have also doubled their salary. As they start their work, Phuong suddenly falls, stricken with severe pain. Worried, An and Nhu take Phuong to a hospital, but they are refused admission for not having an ID card.
