Tin is the third child of a family of seven people. The family is poor and lives in a small wooden house in an austere neighborhood of Bangkok. The father, Den, used to be a construction worker, but he had an accident that prevented him from working and was fired, which led him to resort to alcohol because of his unhappiness. Thus, the family depends on the mother, who is a seller of rice and curry. Tin's life, worried about passing his university entrance exams, will revolve around that of his relatives, causing many problems.
