The story revolves around a group of idiots. We have Karan (Tushaar Kapoor) your typical lover boy, and we have Tanya (Esha Deol) who starts a relationship with Karan after the prom. Oh and we also have a bunch of forgettable actors to fill up the circle of friends. Tashu (Natasha), Yash (Yash Tonk), Pat (Vrajesh Hirjee) and Kush (Ashay Chitre).
After Karan and Tanya decide that they love each other, we learn that bechaari Tashu secretly loves Karan but now she's going to have to suffer silently cause he's preoccupied. Anyhow that's one aspect of the film. At the same time Tanya has been caught cheating on an exam by professor Bakshi (Rishi Kapoor) a shady guy who has a mysterious past. In order to save Tanya, Karan and friends decide that it would be best to break in and replace Tanya's answer sheets.
However something goes terribly wrong and they discover a deadly secret. While getting away Tanya causes an accident, killing someone, and unable to deal with her action decides it's best to leave Shimla (or is it Switzerland) and forget about her past. After she leaves the circle of friends slowly degenerates and Tashu finally gets her boy (Karan of course).
Sound a little like I Know What You Did Last Summer yet? Maybe a little but hold on there is more. A Few years later Tanya returns to India for a friends wedding, and this is the perfect excuse for all the friends to unite, however they're all being stalked by some mysterious dude (in the same getup as the killer from I Know What You Did Last Summer) who is offing them one by one (and I for one was happy that he was getting rid of these brats). Oh and amidst all this bloodshed Tanya and Karan are falling in love again but wait Karan and Tashu have a thing going on. Confused? Well wait till you see the climax! Anyhow the remainder of this film deals with discovering who the killer is and why he is killing the group of former friends.
