When things come to a head, Muththaiyan and Kalyani decide to run away to some far-off place and settle down to marital bliss. Muththaiyan's loyal friend Kamalapathi, who is a stage actor makes all arrangements for their escape. In order to hoodwink the vigilant police inspector Shastri, Kamalapathi disguises himself as a woman and goes to the forest to meet Muthaiyan and appraise him of the plans. When Kalyani comes to the appointed place, she finds Muthaiyan embracing another woman. Not realizing that it is Kamalapathi whom Muththaiyan is expressing his heart-felt thanks to, she suspects her lover's loyalty and runs away in a rage.
