In this thrilling Filipino drama, Keka (Katya Santos), at first glance, appears to be no more than a young woman stuck in a dead-end job at a call center. But she has a secret: She's training to be an assassin, and her mission is to hunt down her boyfriend's murderers. Everything's falling into place until Keka meets and falls in love with Jason (Wendell Ramos), a police detective who surely would frown upon her misdeeds.
