Sakthi is a petty thief in a Chennai slum, who learns the Adimurai, the ancient and oldest form of martial arts. Meanwhile, an evil man and his son challenge Sakthi for a kickboxing tournament, and Sakthi agrees to participate in it.
The kickboxing tournament takes place in a large gymnasium, and Sakthi faces off against several opponents, including the evil man and his son. Despite being outmatched physically, Sakthi manages to hold his own and even win some of the matches. However, he is ultimately defeated by the evil man and his son in the final match.
After the tournament, Sakthi is humiliated and shamed by his fellow thieves, who mock him for his lack of skill. But he refuses to give up, and instead sets out to improve his skills. He spends countless hours practicing and studying the Adimurai, determined to become a better fighter.
Eventually, Sakthi's hard work pays off, and he becomes one of the most skilled fighters in the city. He challenges the evil man and his son once again, this time with a much stronger team of fighters. This time, however, Sakthi proves himself to be the real deal, defeating both the villains and winning the championship.
In the end, Sakthi emerges as a hero in the eyes of his people, and he is hailed as a true warrior. He is now known as "Kickmaster Sakthi," and his legacy continues to inspire future generations of fighters.
