Suffering from a debt of more than Rs. 1 crore incurred by his father, Sandeep Kishan runs a library in memory of his mother. He also runs a YouTube channel where he presents the books available in his library in audio format. Through this, he becomes friends with Faria Abdullah. With her help, he starts earning money through YouTube and decides to use that money for gambling in an attempt to get out of his financial troubles. However, he is cheated by the people running the gambling den and ends up losing all the money he had.
