Plot
Shankar, his brother Muthu, their father Namachivayam, mother, Lakshmi, sister Gowri, betrothed Gomathi, all live in a well-to-do happy family. Shankar becomes a collector to fulfill his father's desire while Muthu became 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. Vedhachalam intends to use his connection to the family to get a few files signed and some properties belonging to the government acquired in his name. The honest upright Shankar insults him causing a rift between the two families. Vedhachalam, having felt insulted, wants to take vengeance by ruining the family. He aims to acquire all the land belonging to Namachivayam to whom his land is as sacred as his own mother. He becomes an M.L.A, uses his influence and gets the land acquired through Shankar in his capacity as collector with the excuse that it is ideal for TB hospital. He later subverts the collector and gets it allotted for his purpose. This causes Namachivayam to die and Shankar to resign. 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.

In the end, seeing the influence of Shankar as a journalist grow, he attempts to kill him only to end up killing his own daughter for which he and his cohorts are arrested. Seeing that violence begets violence, Muthu too surrenders.
