Based in Hazratganj, Advocate Ramesh Kumar gets evicted for not paying his rent, finds accommodation with a Nawab, but is subsequently evicted from there also after forcing a tenant of 20-years, Digambernath, to move out. Ramesh then falls for the latter's daughter, Shanti, dons a guise of an old man, calls himself Mirza, and becomes their paying guest. He is able to win her heart, convinces her dad to let him live there, as well as finds employment next door with Public Prosecutor Dayal. He will soon face challenges when Shanti's sister, Uma, and her alcoholic husband, Prakash, move in; he will not only take to alcohol but also frequent the company of Dayal's attractive wife, Chanchal, and estrange himself from Shanti - but nothing will prepare him for the chain of events that will follow after two sudden deaths and an apparent homicide - shattering and changing everyone's lives forever.
