Bahon Mein Teri Masti Ke Ghere - Full Song | Kaala Patthar When disaster strikes - three men stand up to fight for justice for the coal miners who risk their lives as part and parcel of their existence. Vijay (Amitabh Bachchan) a disgraced ex-naval officer has been court martialed and dismissed from the Navy. Vijay is now working at the coal mine. He welcomes every sign of danger and adversity in an attempt to combat the demons within and pay for an act of cowardliness as the captain of a sinking ship. Ravi (Shashi Kapoor) is an engineer in charge of the doomed project. He tries to alert the management on the impending disaster but in vain. Ravi & Vijay join forces in order to save lives of their fellow workers and fight the establishment. Mangal (Shatrughan Sinha) is an escaped convict who finds shelter from the hands of the law at the coal mine.
