Maria is a loving and dutiful wife to her husband Ermin, a police officer with whom she has two children named Pablo and Rosalinda. Facing financial problems after Maria loses her job, and Ermin not being able to support the family on a policeman's salary alone, Maria is convinced to become an Overseas Filipino Worker after learning that her high school friend Emily applied to become one as well. Ermin is hesitant with his wife's plans initially but eventually relents. Maria then goes to
Dubai to work as a
domestic worker and caregiver. In Dubai, Maria befriends Nanay Leng, a fellow OFW. After buying groceries for her employer, Maria is raped on a van and is later found wandering. She is brought to a hospital, where the doctor recommends that she be returned to the Philippines. While hospitalized, Nanay Leng passes a curse to Maria. The curse, by opening her mouth and letting an orange entity inside hop out from her stomach and into Maria's, would eventually turn her into an aswang. In the process of transferring her power, Nanay Leng loses her immortality, and dies shortly after. In the Philippines, Maria is transferred to a hospital in her native
Capiz, where doctors conclude that she has
amnesia and take note of her aggressive behavior. Ermin brings her back to their home, but a hospital employee discourages him due to their findings and says that his spouse might not even recognize him. Ermin eventually convinces the hospital to take her back home saying that it might bring her memories back. Back at their house, Maria appears normal until she threatens her children with a knife for running around. Ermin learns of the incident, with Maria claiming that the action was not within her control. Alone, her aswang curse begins to take control over her until one day she kills her children and cooks them. When Ermin discovers what she has done, he repeatedly shoots her but she escapes as Ermin calls her a monster. Ermin then buries their children. Shortly afterwards, he witnesses a remorseful Maria crying nearby when the aswang curse takes over once again. Maria receives a wound on her face after her husband hacks her face with a
bolo knife and escapes once again. Following her escape, rumors spread of an aswang causing terror throughout the town. Ermin consults an
albularyo, who says there is nothing that can be done to return Maria back to normal. The police then pursue the aswang. After some encounters, Maria is killed. As an
embalmer works on Maria's body, he finds out that her corpse is nowhere to be found, only to find her still alive. ==Cast==
