In the film, we trace the extraordinary journey of Hanumanthu, a young man hailing from a dystopian village called Anjanadri, which is under the oppressive rule of the tyrannical Gajapathi. From the outset, the story blends elements of mythology, heroism, and modern-day struggles. The narrative begins with a divine origin— a divine gem created from a drop of blood spilled by Hanuman (voiced by Ravi Teja), which falls into the sea after the deity is injured by Indra. This gem, imbued with the power of Hanuman, becomes a central symbol of the potential within Hanumanthu.
The story flashes back to 1998, in Saurashtra, where a young Michael, portrayed as obsessed with superheroes, attempts to fly and impresses with his desire to possess superpowers. His fascination turns tragic when, after a failed attempt that results in an accident, his parents die in a fire, fueling his obsession with strength and heroism. As an adult, Michael, now operating in Mumbai, adopts the superhero persona Mega Man, helping others through technological innovations supplied by his friend Vennela Kishore. Yet, beneath this alter ego, Michael seeks real power—the kind that could make him a true hero or an unstoppable force.
The plot takes a mythological turn as it introduces the divine gem, a powerful artifact connected to Hanuman. This gem, born from Hanuman’s blood, possesses immense capabilities and is sought after by various characters. Meanwhile, Hanumanthu, a petty thief by nature, lives with his sister Varalaxmi Sarathkumar (Anjamma) and harbors feelings for Meenakshi, played by Amritha Aiyer, the granddaughter of the village's headmaster. Meenakshi is brave and rebellious, actively resisting Gajapathi's oppressive rule and inspiring the villagers to stand against tyranny.
Hanumanthu’s journey toward heroism begins when Gajapathi, feeling threatened, plots to eliminate Meenakshi by staging a fake bandit attack. Hanumanthu, disguised, inadvertently intervenes and foils the attack, but in the process, sustains injuries and is thrown into the sea. There, he comes into contact with the divine gem, which grants him superhuman strength when exposed to sunlight, although its powers diminish without it. His wounds heal rapidly, and soon he is recognized by villagers as a hero.
As Hanumanthu’s powers grow, he strives to prove himself to Meenakshi, leading to a series of humorous yet heroic episodes. When challenged by Gajapathi in a wrestling match, Hanumanthu defeats him using the divine gem, earning respect and establishing himself as the new Polygar of the area. But his vision extends beyond mere rule; he dreams of establishing democracy and abolishing the outdated feudal system, a stance that gains Meenakshi’s admiration.
The narrative intensifies as Michael and his accomplice Siri, played by Rohini Reddy, arrive in Anjanadri under the guise of corporate social responsibility. Beneath their benign appearance, Michael’s real motive is to harvest Hanumanthu’s powers. His manipulations culminate during a village festival, where Hanumanthu cleverly hides his true strength, and Michael’s plans are thwarted for the time being. As Hanumanthu matures, he begins to understand the sacrifices made by his sister Anjamma, played by Varalaxmi Sarathkumar, and makes efforts to secure her future with her wedding.
However, tensions escalate when Siri kidnaps Hanumanthu, demanding to know the secret of his powers, while Michael watches from afar. An intense chase ensues, and Hanumanthu uses the divine gem to rescue himself and Meenakshi, revealing his inner hero and childhood protector. Their bond deepens as they confess their love, and Hanumanthu warns Gajapathi to refrain from harming Meenakshi, emphasizing the importance of benevolence in leadership.
The story reaches a climax as Hanumanthu infiltrates Michael’s hideout to uncover his true sinister plans: to destroy Annadri and seize the divine gem for himself. Michael’s cruelty is laid bare when he almost kills Siri, confessing to having murdered his own parents similar to Hanumanthu’s tragic past. The elderly sage, who disguises himself as Hanumanthu, intervenes and helps to recover the divine gem, inspiring Hanumanthu to stand firm.
On the day of Anjamma’s wedding, chaos erupts as Michael kidnaps Hanumanthu’s sister, accusing him of stealing the gem. In a dramatic confrontation, Hanumanthu hands over a faux gem that injures Michael and exposes his lies. Chaos ensues when Michael’s men attack, resulting in Anjamma's death. Consumed by grief and believing he has failed, Hanumanthu discards the divine gem, feeling that it no longer serves him.
In a final act of malice, Michael releases toxic smoke into the village, causing the villagers to freeze in place. With his back against the wall, Hanumanthu is urged by the sage—revealed as King Vibhishana from the Ramayana—to summon his inner strength. With Siri’s help, Hanumanthu fights Michael’s forces, destroying his drones and the spreading smoke. In a daring attempt, Michael captures Hanumanthu, tries to escape with the divine gem in a helicopter, but Hanumanthu, fueled by resolve, battles fiercely and destroys the aircraft, killing Michael once and for all.
The destruction of the divine gem results in an unexpected transformation: the power of Hanuman is absorbed into Hanumanthu, and the emergence of Lord Hanuman himself, rising from the Himalayas, signals the dawn of a divine war. The film concludes with the promise of new battles and the fulfillment of a hero’s destiny, rooted in mythology, heroism, and the timeless fight between good and evil.
