Like Avtaar, his sons have also married rich girls, daughters of Seth Laxmi Narayan Pinchoo Kapoor. But, they are totally henpecked. When Avtaar discovers this, he leaves his home. Radha and Sewak also follow him. With help of a moneylender Bawaji Sujit Kumar, Avtaar starts his own garage. Avtaar faces an uphill task, since he has no money to buy equipment, is aged and his right hand was paralysed in a freak accident. Sewak helps his master by illegally donating blood to arrange for money, but when Avtaar thinks that Sewak resorted to robbery, Bawaji tells the truth. Moved, Radha and Avtaar regard him as their own son. Meanwhile, both Ramesh and Chander are enjoying their own life. Avtaars luck changes again when the carburator he is working on gives a successful result. Soon, Avtaar starts manufacturing the engine parts. This gives way to an industrial empire headed by Avtaar, Radha and Sewak. To help other old people like him who were spurned by their own families, Avtaar starts some social institutions.

Although Avtaar is not willing to help them. Next day, Avtaar goes to office and does not return. Radha calls him many times and finally reaches office late at night. She tries to convince him that she is a mother too. But he doesnt listen to all that. Deep in emotions, Radha accuses him of having turned heartless. Same day, Bawaji meets Radha, whereupon Radha tells him the whole story. Bawaji has to tell the truth to her as he cannot bear Avtaar being insulted despite his big heart. On learning the truth, Radha realizes her mistake and tries to call Avtaar. Sewak informs her that Avtaar had a heart attack. Everybody goes to Hospital, where Avtaar had already written his will and hands it to Radha and dies. The story comes to the present, where Radha garlands Avtaars bust and the film ends.
