Devadathan Chemmathiripadu, a Vedic scholar, is widely respected by everyone, played by Narendra Prasad. He has earned the title Somayajippadu after completing Somayagam and leads a simple life, deeply anchored in family and ritual. He has two sons: Somadathan Suresh Gopi and Chithrabhanu Jayaram. Bhanu Namboothiri serves as the chief priest in the nearby temple, a steady figure in the village’s spiritual rhythms.
During his Delhi days, Somadathan drifted toward atheism, aligning himself with radical groups that questioned the authority of the Vedas. When he returns to the village, the rituals that once bound his family begin to irritate him, and he openly denounces the Vedas as superstition, trying to recruit others into his skeptical fold and challenging the comforting routines that define village life.
Somayaji, the family patriarch, initially brushes off his son’s rebellion, but as the dissent grows, the tension becomes unbearable. He urges Dathan to return to a Brahmin’s life, to which Dathan butts back that he is no longer a Brahmin and had long since abandoned his Yajnopavitam. The clash fractures the old order and pushes Dathan to step away from the house he grew up in.
Dathan marries Gayathri [Geetha], an atheist and his lover, and together with fellow radicals, they move into an old haunted house. The couple, determined to defy superstition, cleans up the place and takes a hammer to the idols of Nagas and the small shrine that once anchored the community’s ritual life. Their actions are a defining act of rebellion, a bid to prove that belief can be toppled by collective will and rational critique.
Meanwhile, Bhanu Namboothiri falls in love with a girl in a neighboring village, Gouri, and asks his mother to speak to Somayaji on his behalf. But Somayaji reveals that Bhanu’s horoscope is not favorable—danger looming at the age of 27—an insight that crushes him and leads to his suicide that very night. The tragedy seeds a growing anger in Somadathan and deepens the rift with his father.
Gayathri becomes pregnant twice, but both pregnancies end in miscarriage, a fate villagers attribute to Sarpadosha. She dreams of serpents and begins to believe their act of destroying the idols of Nagas was the reason for the miscarriages, a superstition that gnaws at her sense of reason and safety.
One evening, Somadathan returns home to find Gayathri lighting a lamp for the idols at a shrine that has been cleansed of superstition. She tries to justify her actions and asks him to accept her perspective, but he remains adamant: to stay with him, she must follow his principles. The tension between love and belief grows sharper, pushing their relationship toward a breaking point.
Gayathri seeks refuge at Somayaji’s house, where Somadathan’s mother welcomes her and performs special pujas for her because she is pregnant for the third time. She gives birth to a boy, a moment that raises questions about lineage and tradition. Somadathan argues that the child should not be raised as a Brahmin and that no Vedic rituals should be conducted for him, signaling a generational rift in how the family views inheritance and religion.
As the village gathers for Athirathram, the highest form of yaga meant to please Lord Indra and summon rain, a group of atheists led by Somadathan rises to oppose the ceremony. They challenge Somayaji, pressing him to defend the value of rituals against a world increasingly skeptical of ancient rites. Somayaji lays down a provocative test: if heavy rain comes without the Vedas, will he abandon the ritual life? He poses a parallel question to Dathan as well, asking whether rain would force him to choose the old path again, and Dathan nods in reluctant agreement.
On the last day of Athirathram, the skies open in a torrent of rain. The test and its rhetoric collide with reality: Somayaji triumphs in his final vow, sacrificing his life in the fire of the inner altar. In that moment, Somadathan chooses his father’s way, stepping into the role of the family’s next priest and reaffirming the cycle of tradition, even as the younger generation questions its relevance. The story closes on a note that honors endurance, lineage, and the cost of choosing between belief and rebellion.
