Vachan

Kamla (Geeta Bali) lives a poor lifestyle in a small town in Uttar Pradesh along with her widowed dad, Dinanath, who works as an accountant, and two younger brothers, Kumar and Kishore. Her fathers biggest dream is to get Kamla married to her lover, a wealthy man named Prem (Balraj Sahni), and ensure that Kumar and Kishore get properly educated. As Dinanaths eyesight becomes very weak, the quality of his work deteriorates and he loses his job. However, his employer, Laxmidas (Madan Puri), promises to hire Dinanaths son Kumar once he completes his education. On the day of the results, Kumar tragically passes away in an accident.

Devastated and desperate, Dinanath tries to commit suicide, but he is hospitalised. Later he recovers but loses his vision completely. Kamlas wedding is consequently cancelled, and Prem reluctantly gets married to a woman named Shyama. Kamla starts working and takes it upon herself to look after her dad and Kishore. Years pass by, Kishore (Rajendra Kumar) has grown up, graduates, gets a job and marries a young girl named Tara (Neelma), who happens ro be the niece of Kashiram, Prems friend.

The family settles down to a fairly harmonious relationship which is shattered when Kishore and Tara accuse Kamla of stealing household items; following this incident, Kamla and her dad leave the house, and Kamla soon gets a job as a nurse for a sick Shyama, while her husband Prem is absent, without knowing that she is actually her ex-lovers wife.
