The film stars Fahadh Faasil and Sai Pallavi with Atul Kulkarni, Renji Panicker, Shanthi Krishna and Sudev Nair in pivotal roles while Prakash Raj makes a cameo appearance.

[3][4][5][6] Back in 1967, Lakshmi arrives home to witness her niece, Nithya, playing with a piece of thread, having been completely dissociated from reality, while surrounded by the dead bodies of her family members.

The story then shifts to an eerie mental asylum set in the wilderness 5 years later where Dr. Kannan Nair, a psychiatrist, has come to inspect the place.

Nithya, upon spotting an intruder in her space, hits Nair and he falls unconscious on the cell floor.

When Dr Benjamin questions this act, Dr. Nair mocks him and says autism (Nithya's diagnosis) is not a mental illness requiring confinement.

Dr Nair reads the diary he found from Dr. Benjamin's desk and it reveals Nithya's history to the viewer.

We see that Varma loved his daughter and refused to believe she was mentally disabled, treating her just like a normal child.

While Nair was reading the diary, standing in front of a dock, he slips into the water and the hospital guard ends up saving him.

Nair tries to escape from the place at night with some medical documents, but is chased by the guard dogs and watchman suspecting him to be an intruder.

After this appalling turn of events, Dr. Nair grows close to Nithya and takes her out on the hospital grounds and an obvious romance is bubbling between them.

A conversation between the nurse and Dr. Benjamin (who appear to be lovers) reveals that he had erased Nithya's memories completely.

Nair searches for her, but is misled by Benjamin and chases a car that turns out to be carrying a catatonic Jeevan.

Upon running back to the facility, he is helped by the patients who are all fond of Nithya and they lead him to the place where Benjamin conducts his experiments.

In a rather mind-boggling twist of events, it is revealed that he is the original Dr. Nair and the imposter was actually Vinayan, Nithya's cousin.

We then see that Vinayan and Nithya are happily living together in a beautiful house on the hills at peace, finally free from the external world.
