[3] Shankar, his brother Muthu, their father Namachivayam, mother Lakshmi, sister Gowri, and betrothed Gomathi, all live in a well-to-do happy family.

Shankar becomes a collector to fulfill his father's desire while Muthu becomes a farmer and turns into a revolutionary, seeing the atrocities committed by the corrupt politicians and officials.

Gowri falls in love with Ramu, son of Vedhachalam, a businessman who is married for the second time to a young woman and has his father-in-law as his guide.

He starts a magazine to expose the corrupt nexus above him with the support of Kalpana, Vedhachalam's foreign-educated doctor daughter who cannot bear to see her father's evil activities.

[5][6] The song "En Manadhu Ondrudhaan" is partially based on "Für Elise" by Ludwig van Beethoven.
