Kal Aaj Aur Kal 1971 Directed by Randhir Kapoor
Widower Ram Kapoor lives a very wealthy lifestyle in Bombay, but is very lonely, as his only child, a son named Rajesh, lives abroad, and his aged dad, Diwan Bahadur, lives in the village. Ram frequently throws lavish parties to overcome this loneliness. This changes when Rajesh returns home, and he is able to convince Diwan also to return so that the three could live together. Shortly thereafter differences crop up between Rajesh and Diwan - initially on love and marriage; then on Caste issues; then the marriage of Rajesh, which is arranged with Diwan's friend, Thakur Janak Singh's daughter, Rukmani, while Rajesh wants to marry Monica. Things come to such a pass that Ram decides to leave, takes to women and alcohol in a big way, and becomes the subject of a big scandal.
