Orphaned Branch Manager of Dadar Sahakari Bank, Rakesh Patil, gets married to Jaya, a woman from an orphanage, and they soon become parents of Nandkumar. They long for a mother`s love, and advertise in the local newspapers for one. They get a good response, and pick a woman, name her `Aai`, and permit her to move in with them. The Patils are not aware that the woman they have permitted to live with them is an escapee from a mental institute, is secretly meeting with a knife-wielding ex-convict, Malhari, and has a son, Mohan, who is the local hoodlum and extortionist, and soon their harmonious and idyllic lifestyle will be shattered and turned upside down.
