Rohit meets Chandni at a wedding of her relative, and falls instantly in love with her. He pursues her relentlessly until she agrees to date him, and eventually they become engaged to be married. His family is very much against this because of the differences in their social status, but Rohit doesn't care. One day, Rohit calls Chandni and asks her to wait for him on the terrace of her house, which she does. As she's waiting, the afternoon's silence is broken by the roaring blades of a helicopter. Rohit appears and proceeds to shower Chandni in red rose petals from the copter. When he disappears, she is surrounded again by silence, but she has a feeling something has happened.
Seconds later, Chandni hears the phone ringing and runs to answer, knowing it is Rohit. She is told that he is in the hospital. His family at the hospital greet her with stony expressions and accuse her of being the cause for Rohit's falling from the helicopter. Learning that he is paralysed on his right side, his family continues to berate her. Rohit too berates her, which is too much. Intent on erasing every memory of Rohit, Chandni decides to move to Mumbai.
There she starts working for a travel agency headed by Lalit, a handsome and charming man. He has his own heartache. He soon falls in love with Chandni and asks her to marry him. She finally agrees to his and his mother's delight. On a business trip in Switzerland, Lalit meets Rohit, who has traveled there for treatment for his paralysis and no longer needs a wheelchair now. The men tell each other their stories and sing with the joy of love, not knowing they are both singing about the same woman.
Back in India, Rohit shows up one evening at Chandni's door. To her amazement, he stands up and does a little dance. They are keyed up with emotion and Rohit proposes to her. Chandni tells him she is committed to someone else.
When Rohit becomes angry, Chandni asks him what he would have done in her place. He regretfully leaves. As Rohit and Lalit had become good friends in Switzerland, Lalit invited him to his wedding. Lalit invites Chandni to meet this new friend.
Rohit and Chandni pretend to be strangers to spare Lalit. On the day of the wedding, Rohit has drunk too much and stumbles down a flight of stairs. When Chandni screams and yearns for him to be saved, Lalit realises she really belongs to Rohit and lets her go.
