Hindi cinema has a tendency towards stories that stretch over long periods of time. Days, at the least, but often months, often many years too (that old trope of children growing up has been a part of too many films to name). It is the unusual film, especially in the 50s and 60s, that extends over just a few hours. Solvaa Saal was one such; Gateway of India is another. Both films are about runaway girls who meet the loves of their lives in the course of one night. That, though, is where the resemblance stops.
The first time I began watching this film was on Doordarshan, many years ago. It surprised me, largely because it featured Waheeda Rehman in a very Westernised avatar I had never seen before. It also had an intriguing story. And Dharmendra, always one of my favourites. And Helen. And Johnny Walker.
