Each episode was made of two parts—the first ten minutes of each 30-minute episode was set in the year 1970; the second part of each episode was set in 1995 and related to the events shown in the first part. While the first part revolved around the events of the Anaimudi Alampriyar household as seen through the eyes of the young Rajendran (played by Master Lokesh), the second part was mainly concerned with the customs, beliefs and traditions of the village and events unfolding in the Anaimudi Alampriyar household as seen through the eyes of the sceptical medical student Reena (Devadarshini) and her superstitious Chief Doctor, Nanda (Mohan V. Ram). The story begins with Reena's arrival in the village in the company of her colleague and best friend, Ratna, daughter of the village headman, Anaimudi Alampriyar, who seeks sanction from her village's guardian deity Karuppu Sami to marry her lover Aravind.
