Colonel Saab (Nasir Hussain) is also a doctor in a psychiatric hospital in India. His particular interest is in treating patients with a acute mania, which he describes is caused by the male child's longing for the unconditional love he gets from his mother, and after he separates from her, he searches for this love in other women, until he meets the one who he feels is capable of offering the same. But when that does not happen, the male child becomes cynical, full of hatred, and distrust and develops acute mania. His hospital nurse, Radha (Waheeda Rehman), had successfully treated one such patient by the name of Dev (Dharmendra), and now they have another one by the name of Arun Choudhury (Rajesh Khanna). A reluctant Radha is asked to act as his caring mother-like nurse, to gain his trust, love him, and then make him ready to face everyday life.
