The film tells the tale of Dr Ramdas and his family being terrorized by a series of mysterious phenomena in their new house.

The woods that the house is surrounded by was previously the site of a number of serial killings of children, attributed to a psychopath.

The film begins with a number of children who are kidnapped and murdered by slitting their throats in a village locality in Andhra Pradesh.

Saju tells Ramdas that he suspects that the killings are the acts of a psychopath watching the children die of blood loss.

The psychopath is killed in the subsequent car chase after an explosion, and his burnt remains are found in his jeep.

The next day, while Ramdas is at work, Shyama begins to experience strange phenomena in the house, such as the bathroom shower turning on, a big photo frame in the prayer room crashing to the floor, and seeing the carcass of a goat on the front steps.

Soon after, Ramdas hires Gopalan, a Malayali cook from back home, to help with household chores.

After being beaten up, he meets and befriends a fellow Malayali who warns him that the Hillhouse View area is haunted and refuses to accompany him back there.

When he makes it back home, he spots a fire in the upstairs room of the house and alerts Shyama, and they are able to put it out.

After sensing that Ramdas does not believe him, he explains that Vastu is more of a science than superstition, and that he utilises knowledge about air pressure movements, furniture placement, heat and light etc.

He explains away the incidents such as the spontaneous fire being the cause of improperly placed window panes, and conducts his procedures to make the house safer.

Though initially sceptical, Ramdas is convinced as he notices the changes in the house's atmosphere after the Vastu ritual is complete.

Upon investigating a crashing sound upstairs, he is shown being chased by an unseen presence and runs out of the house.

Ramdas reports his suspicion to Saju Paul who dismisses it, insisting they confirmed the death of the previous killer.

Saju Paul picks up Shyama and the kids to take them to a safe house, but are stopped on the road by the killer.

Ramdas rescues Shyama and the kids and begin driving away, but are stopped by the injured but alive killer.
