A good and bad brother morality play. Younger brother Maradhur (MGR) marries the rich Malathi (Jayalalitha) but refuses to move into his father-in-law’s (Ranga Rao) house. Elder brother Somu uses this impasse to persuade Maradhur’s father-in-law to finance a new garage and to have the entire family move in, forcing Maradhur to follow suit, but the plan is foiled when Somu falls in love with a dancing- girl, driving his family into poverty. Both Somu and the brothers’ beloved mother (Lakshmi) die. MGR’s melodrama, enlivened by several fight sequences, deploys his usual persona of the working-class hero who marries a rich heiress and wins his battles by virtue of his sterling lower-class morality.
