Without citizen ID cards, Abang and Adi live in an old community in Pudu where many foreign workers live. They cannot enjoy general national welfare, cannot apply for passports, and cannot even open a bank account. The elder brother Abang is born dumb, works hard and accepts his fate, just wanting a stable life, while the younger brother Adi is unwilling to bow to fate and illegally sells fake documents. He only wants to make money and take his brother away from this disgusting place. The two people who originally lived an unequal life, because of the enthusiasm of social worker Jia En, volunteered to help track down the data of their biological parents and birth certificates, but her kindness led to an accident, and also put Abang and Adi into a dire fate again.
