The story for Hare Rama Hare Krishna actually came to Dev Anand's mind when he saw hippies and their fallen values in Kathmandu where he was on a visit after protests against his previous film Prem Pujari in Calcutta. He was low in spirits because his film had been opposed and some had burnt Prem Pujari's posters.
The film is about a Montréal-based Indian family, the Jaiswals. The brother Prashant (Dev Anand) and sister Jasbir (Zeenat) have a good relationship as children. However, the parents quarrel and separate leaving Prashant with the mother and Jasbir with the father. Jasbir is repeatedly told that her mother and brother are dead and she eventually believes that she will never see Prashant again.
