He meets Mohanambal (Mohana) (Padmini), a Bharatnatyam dancer, and they fall in love with each other. Sundaram's ego prevents him from developing his relationship with Mohanambal, who asks him to play a Thillana on his Nadaswaram while she dances. Mohanambal's mother Vadivambal (C. K. Saraswathi), an influential and mercenary woman, wants her daughter to marry a wealthy man so that she can settle down in life properly. Blinded by love, she disobeys her mother, creating a rift between them. Unaware of her feelings, Sundaram decides to leave the country along with Karuppayi (Manorama), a folk dancer whom he considers to be his sister. Mohana calls him a coward and challenges him to stay, which he readily accepts. In a temple, Sundaram plays the Thillana and Mohana dances. Sundaram, impressed with Mohana's performance, crowns her the title "Thillana Mohanambal". Suddenly Nagalingam (E. R. Sahadevan), a landlord who wanted to marry Mohana, turns up to stab Sundaram with a poisoned knife out of jealousy. He came to the temple to kill Mohana.
