Aggar (2007)

In this taut and tense thriller, a woman learns that falling in love with the wrong man can have deadly consequences. Janvi (Udita Goswami) is a woman whose life appears to be fine on the surface: she owns a prosperous company and is married to a psychiatrist, Dr. Adi Merchant (Shreyas Talpade). When Aryan (Tusshar Kapoor) enters Janvi's company, however, a sliver of discontent begins to creep into her relationship. Janvi is drawn into an acquaintance for the first time, believing that it would give her something to live for. However, in an unusual turn of events, she discovers she has made a serious error and attempts to end her relationship. Aryan, on the other hand, is unable to let her go too easily, and his attraction to her quickly turns into a deadly obsession that threatens to extinguish Dr Adi's life forever.
