Story
Tarun, an out-of-towner architect moves in with his family to a luxurious bungalow that he has acquired on a rather cheap rent. His wife Namrata?s curiosity over the seemingly low rent is quashed by their kids who readily approve of the new house. Soon 10 yr. old Taman and 6yr old Nimmi who are often at loggerheads find their own activities to do in the new house. Taman spends his time on videogames and TV whereas the curious kitten Nimmi spends her time exploring the various spaces of the house. During one such exploration Nimmi finds a cute looking doll. Soon after the discovery of the doll Nimmi starts including ?Shabbu? in all her activities. The family mistakes Nimmi?s new doll to be Shabbu. But they are left gob smacked as Nimmi introduces the doll as ?Dolly? and points at an empty space and introduces her invisible friend as Shabbu. The parents suspect Nimmi?s playfulness and wild imagination as the reason for her new ?friends?.
Soon Tarun?s younger sister Pooja surprises the familyby visiting them straight after a wildlife photography assignment. The prankster in Pooja decides to scare Nimmi but instead gets jolted by a Shabbu remark. As Tarun, Namrata and Pooja discuss Nimmi?s fixation over her imaginary friend Shabbu; the domestic help Laxman is sure of the presence of a spirit in Nimmi?s life. Laxman?s worries receive severe backlash from Tarun, an ardent rationalist. Soon, each night at the bungalow seem to turn for the worse, all with knocks at unearthly hours, demonic sounds and eerie movements throughout the house. Tarun suspects Laxman to be the mischief-maker trying to prove his points. As Nimmi?s fixation with Shabbu increases, the family decides to consult a psychiatrist.The psychiatrist explainsNimmi?s imaginary friend as a result of her loneliness and terms it as a common technique used by children to grab attention. Laxman?s sudden disappearance and the increasing curiosity in Pooja to find answers for the ongoing activities make her install cameras at various places in the house. The footage from these cameras is proof enough for the already disturbed Namrata to take a decision to vacate the house. The otherwise cool-headed Tarun?s mind starts reeling as he sees the captured footage. The family finally decides to vacate the house. But the house has other plans of its own as Nimmi is found missing.
