In girl's hostel, changing rooms of shopping malls, honeymoon bedrooms of hotels and in the hands of anyone in the form of a mobile phone camera to use it as and when needed to exploit! It's not aimed at any particular woman of a certain class, cast or religion. It could be anyone; it could be your woman next!
Such are the modus operandi of Sudama Pandey (Mukesh Rishi) based in London, who runs a racket all over up to India, trapping innocent women to abuse and in falls a prey!

Dinesh and Dinesh (Mukesh Tiwari and Murli Sharma), Sudama Pandey's trusted men have trapped Sapna who wants to break free. The struggle attracts the attention of Ammu (Amisha Patel) who when reaches to help but finds Sapna being murdered.
Dinesh and Dinesh chase Ammu, their eye witness and thus starts the thrill. A frantic couple Ashish (Ashish Chaudhry) and Aarti (Aarti Chaberia), Ammu's sister, hunt for Ammu all over the town! While Arjun is looking for a clue to nab the gang, he's informed the eye witness, Ammu. Arjun runs to save Ammu so that through her he can bust the racket, not knowing that the girl he's come to rescue lives no more.
