At present in 2016, Dr. Krishnakumar / Krish (Siddharth), a successful neurosurgeon, and his wife Lakshmi (Andrea Jeremiah) live peacefully in their beautiful house under the mountains in Rosina Valley.

Jenny starts to act weird soon and sleepwalks to the edge of a cliff where her father Paul D'Costa(Atul Kulkarni) and Krish save her yet again.

Dr.Prasad concludes she has developed Paranoia with visual and auditory hallucinations and advices Paul to perform an exorcism, since he is sure of some paranormal behaviors happening with Jenny.

Paul finds some disturbing evidences in his house and agrees to call the psychic from earlier, and he reveals the presence of a mother and daughter spirit, asking them to leave.

Meanwhile, Dr.Prasad feels that there is more to the story of the spirits from Jenny's exorcism and upon researching, he finds that there is a witness who knows what happened in Paul's house 80 years ago, an old lady from the village.

So Krish and Dr.Prasad visit the old lady, who reveals that the man of house Lu Wei was into black magic, he attempted to kidnap and kill her when she was a child, but his pregnant wife intervened and let her escape.

Lu Wei now intends to continue where he left off and targets Sarah for his human sacrifice, so that Lakshmi would give birth to a boy.

The screen closes in on the boy's eye, which changes to show double irises, implying that he could be demonic, since he was conceived when Krish was possessed by Lu Wei.
