A Bona Fide Killer

Yoo Bo-na has a secret most mothers would never put on a résumé: she is Kingfisher, a legendary sniper who takes on criminals who escaped justice. After three years on maternity leave, she returns to her deadly job while trying to keep life normal for her husband and young daughter. The problem is that her husband, investigative reporter Kwon Tae-sung, has been assigned to uncover the identity of Kingfisher. As his investigation brings him closer to the truth, Bo-na must keep her deadly double life hidden while juggling family responsibilities and increasingly dangerous assignments.
