Marudheeran (half tiger-demon and half human) is the adopted son of a tribal village chief named Vembunathan. From a young age, he notices the atrocities regularly committed on the villagers by soldiers from the neighbouring kingdom of Vedhalapuram called the Vedhalams, who have supernatural powers. When he becomes an adult, Marudheeran starts to protect the villagers from the Vedhalams. As a result, the villagers respect him.
Marudheeran falls in love with Pavalamalli. And they both get married secretly and tell and take blessings from Vembunathan. Vembunathan tells them to visit the temple before announcing their marriage to everyone. When Marudheeran is in the temple, Pavalamalli is kidnapped by a group of Vedhalams, who then ransack the village and also kill Vembunathan. Marudheera and his close friends Kodangi and Sama begin a journey to Vedhalapuram. During the voyage, Marudheeran rescues Manthagini, the princess of Vedhalapuram, from a panther. That time, Princess Manthagini falls in love with Marudheeran. Thalapathy Jalatharangan, the evil-minded demon, Commander-in-Chief of Vedhalapuram, notices this. On the pretext of being medicine makers, Marudheeran, Kodangi, and Sama enter the Vedhalapuram palace, where they meet Yavanarani, the cruel Queen of Vedhalapuram and a sorceress. She allows them to stay at the palace, and Marudheeran wins the support of the Queen and the love of Manthagini with his fighting prowess and resilience. Yavanarani announces the engagement between Marudheeran and Manthagini.
Later, Marudheeran discovers he is a half-Vedhalam (half-demon). Marudheeran was the son of Pulivendhan (powerful tiger-demon) and Pushpa (human princess). Pulivendhan was the late prince of Vedhalapuram, Yavanarani's younger brother and Manthagini's uncle. When he stood up to Jalatharangan, who used to terrorise the citizens of Vedhalapuram with the help of his henchmen, Jalatharangan killed him and his wife, Pushpa. Marudheeran also discovers that Yavanarani is actually a puppet Queen under the influence of evil magical power emanating from Jalatharangan's ring. Due to the evil magical influence, Yavanarani developed magical powers and her tyrannical behaviour. She performs yearly Kanya Puja to boost her magical powers. After Yavanarani performs the Kanya Puja for the 18th consecutive year (this time on Pavalamalli), Jalatharangan has planned to eliminate her and take over the throne.
Marudheeran also discovers that he will transform into a Vedhalam (demon) if he stops taking the demon power suppression medicinal leaf that he was consuming from his childhood. Marudheeran transforms into a demon, fights Jalatharangan and kills him, avenging his father's death. Still, before he dies, he opens his ring, releasing all the evil magical power so that Yavanarani can continue to rule Vedhalapuram as a tyrantess without his control after his death. Marudheeran realises that the Queen can be returned to normal only if her wand, which is the source of her magical power, is destroyed. Marudheeran and Manthagini find her performing the Kanya Puja on Pavalamalli. After a bitter sword fight with the Queen, he manages to smash the wand, thus restoring the Queen to herself. In gratitude for releasing her from the evil magical influence, Yavanarani makes Marudheeran heir to the throne of Vedhalapuram.
