Years later Dipinti is 16 years old, and is in love with Amit Mehra. Amit is introduced to the Vermas and all approve of him. Their idyllic and harmonious existence is shattered when they run into strong opposition from Amit s dad, Advocate Mehra, who refuses to permit his 20 year old son to marry the daughter of a mistress, and a woman born out of wedlock. Nevertheless, Amit does get married to Dipinti, and shortly after the marriage Shyam, Rukmani, Radha, Amit and Dipinti are arrested by the Police and charged under Section 496 of the Indian Penal Code. Watch what happens when the Vermas find out that their case is weak and all of them may face imprisonment for bigamy, and arranging the marriage of minors.
