Inkaar (1977)

Haridas Choudhry lives a wealthy lifestyle in Bombay, India, along with his wife, Sonu, son, Guddu, and sister, Geeta. He had started his career as a lowly cobbler on a the corner of a busy street, but is now the owner of a shoe company. His associates want him to make shoes that wear out soon, but he refuses to do so, and would like to buy out National Shoes for 20 Lakh Rupees. He withdraws the money, but before he could undertake the transaction, Guddu gets kidnapped, and the demand from his abductors is for 20 Lakhs. Much to his relief he finds out that his servant's son, Bansi, has been mistakenly abducted in place of his son. Nevertheless he decides to pay the ransom, this time with the help of Inspector Amarnath Gill, his sister's estranged boyfriend, who he had turned down as he was not wealthy enough. The money is turned over to the kidnappers, two associates, Manmohan and Preeti, are arrested, Bansi is found and returned to his dad. But the money and the real abductor, Raj Singh, is still at large - and as long as he remains at large none of them can really be safe for he has a grudge to settle against Haridas, and the missing 20 Lakhs may result in the bankruptcy of Haridas' company, they may have to forfeit their family home, and Haridas may well face a jail sentence for embezzling this amount for personal gain.
