Plot
The movie opens with the mysterious death of a businessman named John Kalathil. As the investigation into John's death unfolds, his wife Elizabeth also meets a tragic end in a car accident. In her final moments, Elizabeth is seen by an auto-driver Hemanth and she implores him to meet a man named Balan and tell him that "it all ends at Seven Hills." However, Hemanth is discouraged from acting on it by his friend Murali since its only a couple of hours to his sisters wedding in the morning, and the police could keep him occupied for ever.
Once his sister's wedding is concluded, he is again discouraged from even reporting to the police by his friend. By the time Hemanth musters the courage to meet Balan, John & Elizabeth's daughter Pearly is attacked at her home but saved in time by none other than her Balan Uncle who happens to be a close family friend. Not trusting the law and order department, he moves her to a secure hideout of his own.
When Hemanth finally reports Elizabeth's cryptic final words to Balan at his party office, the latter takes him to his hideout where he has secured Pearly for the time being, and together, they attempt to uncover the mystery. It turns out that Balan, though aged, is a hard core party cadre, with no hesitation to take matters into his hands if push comes to shove.
What follows is a mishmash of events as Hemanth embarks on a quest to uncover the truth behind the deaths of John and Elizabeth.
When the police gets wind of their location, Balan sends Pearly with Hemanth to another location in a forest, but they are ambushed by the same group of goons who tried to attack Pearly at her home earlier. Almost taken, they are saved this time by the timely appearance of a mysterious stranger Devanarayanan who thrashes the goons, takes their leader captive and takes Hemanth and Pearly to his own secure guest house in the forest. When Pearly later finds a photo of a young Devanarayanan and her own mother Elizabeth in the house, she surmises that he must be the 'Deva' her mother had been talking to lately on the phone after John's death, and that he must have killed her father John to be with Elizabeth. She tries to stab Deva as he sleeps but an alert Deva catches her deftly and reveals that he is a friend, and that John Kalathil had earlier approached him, as he happens to be an independent business consultant and how Deva had saved their company from imminent ruin.
After John's inexplicable death, he had been guiding Elizabeth over the phone to save the company from greedy directors, leading to them badmouthing the duo and even Pearly getting the bad impression. When he himself was attacked at home by a team of goons, Deva decided to delve into the case and solve the mystery.
Releasing the goon leader Deva had taken captive earlier as a ruse, they follow him to a grand building deep in the forest named the Seven Hills. It is revealed that the place is the headquarters of a group of Satan worshippers, and that their leader and the mastermind behind the whole mystery happens to be none other than John Kalathil's father and Pearly's grandfather David Abraham Kalathil, who had gone deranged on Satanic worship and has been arranging the murder of his own son and daughter-in-law, while the real prize always was Pearly herself, who supposedly was born on an occasion special to Satan. As Pearly is about to be sacrificed on the Satanic altar so David would gain supernatural powers, Deva, Balan, and Hemanth save the day thrashing everybody in place and subduing David.
