It is a remake of Uttam Kumar's Bengali classic Ami Se O Shakha (1975),which was also based on the Bengali story of the same name by Ashutosh Mukherjee. When a deprived boy, brought up in a privileged family and indebted for virtually everything he has, lends in a perplexing situation, the life seems unfair to him. There are very few who actually appreciate benevolence showered on them. When it comes to repay such debt, many of us try to find excuse to avoid the difficult situation. But the protagonist of this movie is a noble individual, an ideal hero, who knows that everything he has in life, is owed to a family and when he finds himself in a situation where he has to give up his love and profession, he doesn't look back.
