Wealthy and influential builder Mr. Malhotra has erected a factory on the lake’s shore, letting pollutants and toxic waste seep into the water. He dreams of a bridge spanning the lake to expedite transport, but progress stalls because a sacred tree on the opposite bank sits on land owned by Mrs. Dhillon, a devout Punjabi woman who lives with her son Aman Dhillon and his brother Rohit Dhillon. Aman is a martial arts teacher at a local school and harbors a crush on Kirti, a fellow teacher, adding a tender thread to the unfolding tension.
When Malhotra cannot push the Dhillon family to sell, he hires Raka, a ruthless mercenary, to remove the barrier. Raka arrives at the sacred tree with a chainsaw, but Aman stands in his path. The confrontation turns brutal: Raka pummels Aman, nearly decapitating him, but at the crucial moment a lightning bolt strikes the tree, hurling Raka aside. He crashes among barrels of toxic waste outside Malhotra’s factory, his power—and his danger—increasing with the exposure.
The next morning, Aman wakes up unscathed, certain that the violent incident was a dream. Yet signs of the bizarre linger: a khanda symbol appears on his back—the same emblem carved into the tree and imprinted on him during the attack. As the day unfolds, Aman and Rohit notice a suite of extraordinary abilities: astonishing agility, the capacity to absorb information by touching objects, and sudden bursts of super speed that help them escape ambushes. Their mother confirms the truth they fear: Aman has acquired superpowers. She proclaims him a superhero and begins to equip him for the role, even sewing a costume and showing him a montage of superhero films for inspiration. She also shares the story of his father, Sardar Kartar Singh Dhillon, a Sikh who traveled to Shaolin to master martial arts and earned the name “Flying Jatt.” With pride and a touch of reverence, she urges Aman to accept his father’s legacy and embrace the Flying Jatt persona, a name he eagerly accepts.
Aman’s first public test as Flying Jatt comes when he bravely saves hostages from a terrorist attack at an airport, earning recognition and belief from the people he swore to protect. As his heroism grows, he gathers the courage to reveal his secret identity to Kirti, closing the loop on a personal romance that had begun to blossom in the classroom. The couple’s bond strengthens as the city begins to rely on this unlikely guardian.
Meanwhile, Raka returns, stronger than before thanks to the pollution that feeds his powers. He proves to be a relentless foe, and Aman engages him in several high-stakes battles, usually managing to win but taking grievous injuries in the process. In a devastating twist, Rohit steps forward to take up the cape of Flying Jatt in his brother’s stead, rushing into danger to protect his loved ones. Rohit’s sacrifice is brutal and final: he fights valiantly, but he is overwhelmed by Raka and loses his life. The loss exposes a harsher truth about the world their family inhabits, and the earth itself begins to tilt toward a toxic fate as pollution spreads and people fall ill.
Fueled by grief and anger, Aman experiences a dramatic transformation. He adopts the identity of a Sikh Sardar, channeling the resolve and duty that his father embodied, and resolves to confront Raka once and for all. The final battle takes him into a new, cosmic arena: Raka is briefly carried above the earth, where the absence of pollution robs him of his power. Aman gathers his strength, faces the menace with renewed purpose, and delivers a decisive blow by driving the mystical Kara into Raka’s chest, ending the threat. He returns to a celebratory reception from a grateful crowd, now bearing the legacy of Flying Jatt and the memory of his brother’s sacrifice.
