Enters a cruel tantrik (Kota Sreenivasa Rao), who uses the feud between Jagathalapradhapan and Alai Kallan and plans to kill Jagathalapradhapan and thereby get the ultimate power to rule the world. But all his plans are altered when Mohini's spirit comes back to earth. She prevents tantrum to near Jagathalaprathapan. Meanwhile, Mohini wishes to kill Jagathalaprathapan by luring him to have sex with her in an isolated forest so that she can unite with him in heaven. But the plan gets spoiled by Azhagu Nachiyar's smart tricks.
