Devendra Dutt (Sanjeev Kumar) is a famous writer and a misogynist. One night, while returning from a meeting, he sees a young woman thrown out of a moving car. His uncle insists they take her home and get her medical attention. He hesitatingly agrees and takes her to their home.
Next morning, the young woman (Jaya Bhaduri) regains consciousness, but is suffering from amnesia. She can't remember anything except that she is married to Devendra. She can't remember anything from her past - not even her name except that she is Mrs. Dutt. Everyone tries to convince her otherwise, but she insists she is in her own home. Seeing her fragile state, Devendra and his uncle decide to let her stay until someone comes for her. They call her Anamika (meaning a woman with no name).
They post an advertisement for her in the newspaper, but receive no response. Meanwhile, Devendra slowly grows close to her and secretly wishes that she would stay forever. On his uncle's suggestion, Devendra takes her to Shimla on holiday to further help her fragile recovery. There, he sees Anamika's photo in a studio and on further inquiry comes to know that she is the wife of a businessman. Though heartbroken by the realization that she is married, he goes to meet the businessman. Here, he is shocked to learn that Anamika isn't the businessman's wife, but his employee/escort who accompanied him on his holiday to Shimla the previous year. Being already dumped by a former fiancée, Devendra believes that Anamika, like all women, is immoral and after his money and throws her out of his house.
