Heeru, Naren, and Chandranath were friends. From his college days, Chandranath had been aspiring and ambitious. He is also a man of strict principles in life. He leaves his brother and sister-in-law and goes away to gain immense power and knowledge. In the meantime, he marries and is blessed with a kid. However, Chandranath's quest to learn more drives him to leave his new family as well as he sets off to achieve new goals in life. He not only fails to fulfill his request but ends up losing his family too. On the other hand, Naren hails from a rich family and is a happy-go-lucky-natured man. He appreciates the finer aspects of life. He falls in love with a courtesan and brings her home. Caught between the two friends who have opposite ambitions in life, Heeru wonders which path would bring contentment in one's life. However, Heeru loses control of his life and slowly realizes that his life has become a mirror of Chandranath's life.
