Mohan Sharma Tarun Bose,
a successful businessman in Bombay, marries Aruna (Surekha Pandit) late in
life, and is leading a happy married life, when, unfortunately, his wife dies
during childbirth leaving behind a young daughter, Uma (Sharmila Tagore), whom
he cannot bear to see, except when he is drunk. Naturally, the daughter grows
up all by herself and becomes highly introvert. As time passes, Mohan
Sharma's health starts failing due to overwork and alcoholism; doctors
suggest change of weather to a hill-station, Mahabaleshwar.
Meanwhile, Arun (Deven
Verma), son of Mohan Sharma's friend Hari Mehta, and who is set to marry Uma,
returns home after studying engineering abroad for five years, and joins them
along with his friend, Ashok (Dharmendra), a writer and a teacher. Here
things change when young Ashok enters Uma's life, but she cannot do anything
to jeopardize the already fragile relationship between her and her father.
