Madadgaar (1987)

Wealthy practical prankster Sunita falls in love with a lowly truck-driver, Anand, much to the chagrin of her dad, Sohanlal; mom; Chacha; and Mama, who publicly humiliate Anand. She defiantly decides to elope with him, and asks him to meet her in their family bungalow in Koofri. But Anand informs her family and comes to know that her dad has been re-located abroad for medical treatment. The rest of the family ask him to accompany them to Koofri. They will soon be mystified when Sunita arrives and refuses to recognize anyone including Anand himself.
