Raghavan (Sananth), an aspiring filmmaker, narrates a horror story to a film producer (Singampuli), who asks for a run-of-the-mill comedy in which the hero and the comedian keep talking throughout, and the audience should not be able to discover who the actual hero is. Sajith (Abhishek) is an electrician living a miserable life, while Vimal (Ramesh Thilak) is a graphic designer. Srinivasan alias Srini (Arulnithi) is involved in a platonic relationship with Jillu (Jangiri Madhumita), a married woman, in return for money. Out of false bravado, the four decide to visit a dilapidated mansion in De Monte Colony, which is rumoured to be haunted. They sneak into the house and get separated in the darkness and have a chilling and forgetful experience, although all of them manage to come out seemingly unscathed.
