The wealth and position of Pratap Chandra Chaudhury, the big coal mine owner was not only built on the coal that was dug out from underground but on sin equally black. But his crime was- never detected by law and he flourished.
To drive his Rolls Royce, a sign of his opulence, a driver was appointed. His daughter Sandhya found this driver strange. He did not talk like any driver that she had seen before. He looked like a gentleman, talked like a gentleman and he fascinated her.
For a long time Sandhya's resentment against her father for his maltreatment had been growing. This new driver fanned the embers into a roaring fire that consumed all her fears till the meek and shy Sandhya dared to revolt against her father. She ran away from home and when she came back she was the lawfully wedded wife of the driver. Arrogant and proud Chaudhury could not stand the humiliation and when he learned the real identity of the driver the shock killed him.
Who was this extraordinary driver? Did he love Sandhya or did he marry her because he wanted something else? Perhaps it was Sandhya's fate that she would have to pay heavily for her father's sins. And how she paid it, you will know in "Satranj".
