The film opens with the brutal murder of Neeraj Shah (Sachin Dubey). His body is dumped in the trunk of a car. This crime isn't committed on impulse: Whoever did it had good reason.

We then enter the life of a bank executive Pratyush Shelar (Atul Kulkarni). He gets home late on his anniversary because he had to console an old college classmate about her marital woes. His own marital woes are worsened when his wife Antara (Suchitra Pillai) kicks up a big fight and leaves their home with their daughter Saanjh.

Pratyush is upset about this. His colleague Aslam Durrani (Harsh Khurana) picks up on this and suggests an exotic dancer Teesta (Shweta Menon). Pratyush is too upset to be interested. But Aslam is determined; later that night he calls Pratyush and pretends as though some thugs are about to kill him. He asks Pratyush to come immediately to a certain location.

That location is 88 Antop Hill.

Pratyush arrives. 88 Antop Hill is a halfway house mainly occupied by exotic dancers and escorts. Pratyush walks into the flat Aslam had mentioned; it is Teesta's lair. She attempts to seduce him but he refuses her advances. Upon her request, he takes her to the Moksha club and buys her a drink. (He doesn't drink.) She remarks that the bartender Sol (Rahul Panday) knows all her secrets. While leaving the bar, their car is attacked by an apparently drunk man, who seems to know Teesta. Teesta urges Pratyush to leave fast. When he brings her back home, he realizes that his car keys are missing. He waits as she looks for them.

When Teesta gets into her bedroom, she is mysteriously murdered. She stumbles into Pratyush's arms, fatally stabbed, and collapses. Scared and confused, Pratyush leaves immediately. One of the neighbors, a weird and on-and-off senile old fellow called Murli Mansukhani (Shauket Baig) sees him leave.

When the cops begin to investigate, they find that Teesta had a roommate Sonali (Jasmine) and that Sonali is engaged to a prominent businessman, K.K. Menon (Sanjay Singh). The investigating officer, and the hero of this movie, Inspector Arvind Khanvilkar (Rahul Dev), starts his work. The prime suspect is an unwitting Pratyush because he was the last person to see Teesta alive.

A somewhat convoluted plot evolves. Sonali has several dark secrets and a good-for-nothing brother Prashant (Subrotto Dutta). Teesta was somehow connected to Sonali's dark past. Menon knows this and wanted to wipe out everything, including Prashant. He has Prashant kidnapped, and later he tells So
