One beta woman is currently laboring one night. That Beta name is Haeun. Haeun is poor and she has no family at all. Her husband died in an accident while she was pregnant. She and her husband got to know each other by selling fish in the market. They loved each other so much until they found out that Haeun is pregnant. The couple was so happy about the news. Their life is not good but they promise each other to do everything that they could do for their upcoming baby. Until one night, Haeun heard a shouting from the sea side. A group of people were shouting that one of the boats from the sea got shrink. Haeun suddenly feels weak. She knows her husband was riding that boat. That was the last time that she saw her husband alive. And because of that, Haeun life becomes so miserable. But for her baby, she needs to survive.

The beta Haeun is laboring in a small house in a secluded province, an unsafe and unprotected place. The place where everything is run by devil people. Full of drug addicts, money collector, snatchers, everything bad you could even imagine. The beta has no choice but to live in this kind of place. She is living here because of the cheap apartment and the work for being a seller of fish is no chance to have enough savings to leave in this place. That's the thing she hated the most but she had no option but to accept it. 

A one old lady is helping her with laboring. When the newborn baby is out, a loud cry comes after. The room is filled with beautiful noise from the baby's cry. The beta hurriedly asked the old lady if what her baby gender is, what her newborn is. Haeun has no money to do ultrasound while she was carrying the newborn due to lack of finance. The old lady looked to beta and said that the baby is a healthy boy
