Youngnam (Doona Bae) was a top graduate of the Korean police academy, but due to "misconduct" is transferred to a post at a small seaside village. On her first patrol she encounters the mysterious Dohee; a young girl excluded by her local community. As Youngnam adapts to her new life, she witnesses Dohee's situation and is compelled to protect the girl from her family. All is well with this unconventional arrangement until Dohee's drunken father decides he wants her back.
