Miss & Mrs. Cops 2019

Mi-young, once a legendary detective, is stationed behind a desk in the civil complaints department after having a baby. Ji-hye, a hardheaded young detective, is consigned to Mi-young's team as disciplinary measure. At home, they are sisters-in-law who are always at each other's throats.

One day, a distressed young woman visits the department but instead of filing complaint, she leaves hurriedly and throws herself into oncoming traffic. Mi-young and Ji-hye find out that the woman is the victim of a digital sex crime and her sex video is scheduled to be released online in 48 hours. When all the other departments refuse to take the case, the sisters-in-law open their own investigation into the case.
