[2] Shakuntala (Suchitra Sen) and her husband Ajay (Shekhar) elope and move into a new house together.
The landlord Mahadev Chaudhary (David) helps the couple move to the rented house, which is the main protagonist of the film.
While Shakuntala makes the house into a beautiful home, her husband gets busy with work.
The couple hears the sound of a violin in the night and asks the tea-stall owner about it in the morning.
The other members are his elder widowed daughter-in-law (Nirupa Roy) and younger college-going son Bhanu (Kishore Kumar).
Bhanu is finishing college and simultaneously looking for a job, while his old father manages the expenses.
Although there is sadness in the home, Bhanu, with his wit and humour, maintains a light atmosphere for his sister-in-law.
Note: This part of the movie features a song by Kishore Kumar, "Munna Bada Pyara, Ammi Ka Dulara".
The child is also attracted by the music and when he finds out about Pagla Babu from the tea-vendor, he insists on meeting him.
Uma is shocked to realize that Pagla Babu is none other than Raja (Dilip Kumar), her ex-lover.
Ironically, Raja, who is on the verge of dying, pumps life into the child and fills his dark world with hope.
