Millionaire Achuthan Nair (Thilakan) of the Manikyamangalam household, shocks his grasping relations ready for his demise, when he reveals that he has a bootleg daughter, Shoba, from an outdated affair. His relations rent an imposter, Balagopalan (Mukesh), to pose as Shoba's husband & inform Nair that Shoba is useless, thus ending Nair's look ahead to his daughter. Prabhakara Menon (Nedumudi), Nair's pal, then again, tries to forestall Balagopalan from saying this, fearing for Nair's fragile well being.
