In-ae (Lee Si-young) is released from prison. She is very happy to be able to meet his younger sister Eun-hye (Park Se-wan) who has mild learning difficulties. In-ae misinterprets Eun-hye’s reluctance to go to school as a normal teenage rebellion, little aware of her sister being mercilessly oppressed by the delinquency that has handed her over to their friends.
Forced to participate in deception luring employees to the next hotel to rob or blackmail them, Eun-hye just wanted to go home but was eventually kidnapped by the immoral gangsters they were targeting so wrongly.
Worried when Eun-hye didn’t return to the house or answer the phone, In-ae wore a dress and pretty red shoes she bought and also went looking, quickly realizing something that wasn’t wanted had happened to her sister.
The teenage girls run away and usually they go back alone, the police logic explains a little care that Eun-hye is a vulnerable teenager and also In-ae has evidence showing that she has been kidnapped by thugs. If In-ae wants her sister to return, she has to do it herself.
Eun-hye finds herself handed over to the dumb politicians by them. She in turn considers her right to rape as proof of her status, her position untouched and also has the right to violate the strongest taboo without fear of its effects. In-ae doesn’t have all that.
She wants her sister back but also she wants to give lessons to terrible men so they stop treating women. In-ae has no mercy for those who exploit.
