Imagine a place so dark that sunlight or hope never touched it. Imagine a place so dark that even dreams are swallowed by its terrible darkness.
Imagine a mining town, where the mines are as black and deep and exploited as the lives of the miners who go down it, forced to dig deeper and deeper by the wealthy, greedy owners who care for nothing but profit. So deep in fact that with each passing day, the bowels of the earth threaten to close over their heads in angers, so deep that every trip down the mines is a desperate gamble of life and death.
But as the saying goes, where there's life, there's hope, even lives as grindingly grim as that of the miners . And hope comes to town as three men.
Vijay (Amitabh Bachchan) an ex-naval officer who is court-martialed and dismissed from the navy for his role in as captain of a ship that sank and many lives were lost. Vijay is looking for a place so dark that even the hideous demons inside him that taunt him so terribly will get scared and go away. He finds that darkness in the depths of the coal mines where he now works as a coal miner, where he welcomes every danger, every threatening rumble of disaster as a chance to pay for his past Ravi (Shashi Kapoor), the engineer in-charge of these doomed mines. Doomed because the greed and mindless exploitation by its owners have made the mines into potential death traps. Ravi, seeing the terrible danger looming ahead, tries to alert the management but with little use. He is paid for his alertness by being fired from his job which is when he joins forces with the workers and Vijay in order to save the lives of the minors and fight the establishment.
Mangal (Shatrughan Sinha), an escaped convict who is also looking for a place to hide, but unlike Vijay, not from himself but from the eyes of the law. And discovers that under his boisterous and egoistic exterior is a compassionate human being for whom the law of justice is more important than the law of the jungle. He ends up joining Ravi and Vijay in their fight for right.
As these three men set off on their crusade, each of them also find love. From the trusting, simple miners and their families who see these men as messiahs and from three women. Sudha (Raakhee), a doctor who is as kind and caring as she is beautiful and sees Vijay's bleeding, repenting heart behind his stone-hard exterior, Anita (Parveen Babi) a reporter who falls in love with Ravi's fearless, clear-eyed belief in justice and in himself and Shanno (Neetu Singh), a gypsy whose sparkling eyes and racy sales pitch snares even the hardened heart of Mangal.
Kaala Patthar, inspired by a real-life mining disaster, is an intensely dramatic film about the human heart. That as long as it beats with love and with hope, there will always be a dawn waiting at end of the blackest of nights. With a multi-star cast, a lively musical score and a nail-biting climax, Yash Chopra has made Kaala Patthar a memorable exception to the exquisitely soft, glamorous love stories that have become his hallmark
