Based on Komappan, a 1912 poem by Kundoor Narayana Menon, the film tells the story of Palattu Koman, a folk hero and skilled kalaripayattu warrior from the ballads of North Malabar.
The plot unfolds around a longstanding feud between two families: Konkiyamma's Kaippulli Pālāttu Tharavadu and Chandrappan's Thonnooram Veedu.
Chandrappan, the head of Thonnoorām Veedu, plans to seize a treasure hidden in the underground chambers of the Pālāttu mansion.
Disguised, she returns to Pālāttu with her loyal aide Pankan and, with the help of the snakes guarding the treasure, successfully escapes with the wealth.
The film concludes with the death of all members of Thonnooram Veedu, except Unniyamma, whom Koman marries, bringing the story to a harmonious conclusion.
Following the success of Unniyarcha (1961), a ballad-based film from the Vadakkan Pattukal, Udaya Studios chose another ballad for adaptation, focusing on Palattu Koman, a prominent kalaripayattu practitioner from the same folklore.
The screenplay by P. K. Sarangapani was based on the 1912 poem Komappan by Kundoor Narayana Menon, which popularized the tale of Palattu Koman and his love affair with his rival's sister.
