Pangaaligal

Three poor men (Ranga Rao, Sarangkapani and Muthaiah) form a partnership and establish a metal vessel factory. Rao gets hold of the authority and make the other two as wage earners. Rao's son (Radha) goes abroad for studies and comes back as a fully westernized man. He marries the daughter (Anjali Devi) of one of the wage earners as agreed upon earlier. But he is not interested in her and ill-treats her. The son of that wage earner (Gemini Ganesan) goes to Malaysia to learn a trade.
