Nesam and his soon-to-be ex-wife, Amy, a foreigner, travel to his long-forgotten ancestral castle to finalize their divorce. However, Amy harbors a secret motive tied to Nesam’s father’s scientific discoveries. At the same time, Nesam’s former associates—Dawood, Bala, and Thangadurai—arrive at the mansion, each with their own agendas. The plot takes a bizarre turn when a hologram of Oviya appears, and Amy unleashes a monstrous “Franken-Hulk” creature featuring Robo Shankar’s head, causing the story to lose all sense of coherence.
