Dev Narayan (Alok Nath) lives with his widowed daughter Laxmi (Aruna Irani) and her children Radha and Prashant. Dev also looks after two orphaned children, Gopal and Nita. Laxmi believes that Dev is taking more care of Gopal and Nita, so she leaves the house with her children. When she spots an orphaned boy on the streets, she takes him in. Radha forms a sisterly bond with him and names him Suraj.
