Police officers Sonny Cruz and Alice Lagaac discover a video tape addressed to Cruz from an unknown sender. The tape contains voyeuristic footage of a missing girl, Judy Evangelista, whose case has since gone cold. At the same time, Lagaac is troubled over her ex-husband Bronson's decision to send their son to study abroad. Bronson later talks with police chief Jemuel Sy, who expresses contempt for his predecessor. Meanwhile, local shaman and bar owner Magic Mike is worried for Cruz, who is haunted by recurring headaches and mysterious figures.

Cruz is left shaken by a disturbing nightmare. A second tape arrives with footage implying an affair between Judy and previous police chief Jorge Roxas, who is missing and presumed to be dead. The station unveils a bust in honor of Roxas but his widow Isabel destroys the bust by shooting it during the ceremony, expressing her distaste over her husband and Jemuel. Later at night, a strange encounter with a mysterious cult leads Jemuel to a ritualistic offering of a goat head.

Bronson is attacked by a masked assailant. Another tape arrives, and the sender remains unknown. Lagaac visits Roman Evangelista's house and finds clues that Judy may be not what she seems. Lagaac investigates Judy's room. The third tape shows an altercation between Roxas and Judy, with the latter being knocked unconscious into the ground. At night, another nightmare leads Cruz to investigate an abandoned greenhouse containing a locked trapdoor.

Cruz pays a visit to Magic Mike. An encounter with Bronson leaves Lagaac fuming. At the station, Cruz and Lagaac watch the fourth tape, with Roxas dragging Judy's body into the same trapdoor from Cruz' dream. Lagaac notices possible clues to the cameraman's identity in the footage. At the greenhouse, they discover Roxas' corpse instead of Judy's. Meanwhile, Cruz' condition takes a turn for the worse.

Lagaac figures out Cruz is the cameraman. Cruz' guilt drives him to burn down the greenhouse and other incriminating evidence. In a flashback, Cruz asks Magic Mike to remove his memories through a ritual. When Lagaac passes out after their confrontation, Cruz asks Mike to perform the ritual on both of them. Lagaac forgets what happened but now experiences the same nightmare and headaches that haunt Cruz. A new tape arrives but the bizarre footage shows her nightmare instead. Judy suddenly appears at the station, disheveled and back from the dead.
