女主在监狱的编号如片名“2037”,少了个“2”字。19-year-old girl Yunyoung, dreaming of becoming a civil servant to support her deaf mother, gets into an accident one day and is framed as a murderer. In the women's prison, where she's called by her prison number '2037' instead of her name, her fellow inmates in cell 10 gather together to help Yoon-young.
