Kryptonita (2015) Spoiler-Free Summary – What It's About

In an alternate origin story, the last son of Krypton does not find refuge in Smallville. Instead, Superman comes to Earth and grows up in Isidro Casanova, a neighborhood of La Matanza on the outskirts of Buenos Aires. Known here as Nafta Super, he is shaped not by pastoral Americana but by the energy, hardship, and close-knit streets of a working-class urban environment. The legendary alien hero becomes a local figure whose extraordinary abilities exist within the rhythms of everyday Argentine life.

Rather than standing alone, Nafta Super belongs to the Nafta Super Gang, an unusual circle of antiheroes who includes Flash, Wonder Woman, Green Lantern, Hawkgirl, Batman, and Martian Manhunter. Each familiar icon has been reimagined through La Matanza’s culture, but the group’s appeal lies in its bond: a collection of powerful, very different personalities united by loyalty to their neighbors and by a shared distrust of a society that often leaves its most vulnerable people behind. Their version of heroism is collective, instinctive, and uncomfortably close to vigilantism.

The film’s tone mixes urban grit with the heightened possibilities of comic-book mythology. Neighborhood loyalty and political suspicion run beneath the color, humor, and larger-than-life action, while Nafta Super’s double identity creates an enduring tension between the symbol people imagine and the man living among them. His friendships offer companionship and comic friction, yet his extraordinary strength also makes trust a more complicated responsibility. Those who benefit from the existing order have every reason to view the gang’s interference as a threat.

Adapted from Leonardo Oyola’s novel, Kryptonita presents a provocative version of the Superman myth: less a conventional rise to iconic greatness than an exploration of identity, belonging, and power in a city where every gesture feels intimate. The promise of the story lies in watching extraordinary abilities collide with ordinary social realities, and in discovering what this unlikely band of heroes becomes when the neighborhood they call home needs them most.
