Synopsis :
“Pyaar Diwana Hota hai” revolves around Sunder (Govinda), a small-town guy who comes to Delhi to make his ends meet. Using his painting talent he snaps a job as a billboard painter. Now all he yearns for is a comfortable life with a woman of his dreams. Little does he know how destiny will put him in front of her!

Payal (Rani Mukherji) is a beautiful US-bred girl with a special liking for Indian classical dances. Her dance teacher in India has told her to particularly observe the facial expressions of the mute people if she wants to be a good danseuse.

Coincidentally, when Sunder bumps into Payal he is too dumbfounded to utter even a word. But Payal construes it in a different way. She takes Sunder’s silence as his handicap, thinks that he is a mute and begins observing his facial expressions thoroughly. Sunder too does not want to break her wrong notion for the fear of losing her friendship.

Slowly Payal begins to understand the man inside Sunder. She appreciates his painting talent and holds an exhibition of his works. She also takes him to the speech therapist Dr. S. Puri (Om Puri) but to no use. Sunder remains mute as a rock. All this while they both keep coming closer to each other until their friendship culminates into love.

But the question before Sunder is how to tell truth to Payal that he not a mute? How will she react when this bitter truth alights upon her?
