Plot

Murugappan (MGR) is a small-time farm labourer who lives with his widowed elder sister Gangamma (T. R. Rajakumari) in a village. Kaïlasam Pillaival (M. R. Radha) is the zamindar of the village, Sabapathy (S. A. Asokan) and Punitha (Saroja Devi) are his children. Punitha is studying in college in a nearby town, while Sabapathy is not educated. Like the father, the children are both arrogant about their wealth and try to rule the villagers. Murugappa tries to question their authority and this leads to frequent clashes with the zamindar's family. Pitamdhi (Nagesh) is a wealthy college mate of Punitha, who is crazy about her. Sabapathy falls in love with Thillaiammal (Manimala), who has been informally engaged to Murugappa for a long time. Both Pillaival and Gangamma ask for her hand in marriage on the same day.
