When her supposedly happy life is disturbed by her past, she must channel the killer within her to avenge the life they took from her.
The story follows Lily (Cristine Reyes), who decides to leave her employer by faking her death in order to live a simpler life. She changed her name to Maria and began a new life with her husband, Bert (Guji Lorenzana), and their daughter, Min-Min (Johanna Rish Tongcua).
However, Maria's ex-partner, Kaleb (Germaine de Leon), spotted her while on a mission to dispatch a politician. He was so enraged by Maria's lie that he wasted no time in wreaking havoc on her life, beginning with the murder of her husband and only child.
Maria is very upset that her family died, so she asks her mentor, Greg (Ronnie Lazaro), for help in getting revenge for them.
