Ravi (Shammi Kapoor) is a single father bringing up his only daughter, Munni along with his mother. His college-going brother Badal (Roopesh Kumar) is shown to be a playboy and spendthrift. At a fund raiser for the local school, Ravi meets Sheetal (Hema Malini) and takes a liking for her. He drops her home and realises she is a single mother, raising her only son, Deepu. It also turns out that Sheetal is Munni's teacher. A sub plot involves worker Gangu (Randhawa), who cannot speak, and his love for Mahua (Aruna Irani). Mahua is shown to be flirting with Ravi. As Ravi with Sheetal get to know each other, their past stories are revealed as a flashback.
Sheetal has been left devastated by the death of her beloved Raj (Rajesh Khanna). They were engaged in a romantic relationship but not legally married. When Raj tells his father about his plans to marry Sheetal, his father refuses to accept Sheetal as her lineage is unknown. Raj disowns his father and his property and walks out. On his way to Sheetal's birthday party, he meets with a fatal accident. Humiliated by Raj's father, a pregnant Sheetal attempts suicide but rescued is by a priest. She has moved to the current city and raising Deepu as a single mother.
Ravi reveals that his wife Mona (Simi Garewal) died soon after giving birth to Munni. She had a health condition which proved fatal after childbirth.
