South Korean director Syeyoung Park offers a devastating vision of the future, where the reunification of the two Koreas does not bring the long-awaited prosperity but instead ushers in an even more oppressive and somber scenario. The action takes place at an indeterminate time after an ecological cataclysm that stained the sky red and turned the ocean waters toxic. The disaster, now too distant in collective memory, barely survives in the consciousness of the characters, yet its effects are palpable: endless droughts, walled-off cities, and a population subdued by a totalitarian regime that transforms scarcity and filth into symbols of patriotic sacrifice.

In this devastated landscape emerges the figure of the so-called Omegas, men and women who, after working in polluted waters, developed physical mutations: fins at the base of the spine. Branded as pariahs, they are expelled beyond the walls that surround the cities and exploited as slave labor. State propaganda demonizes them, using them as the external enemy that feeds fear and secures obedience, replicating the logic of hostility that for decades divided North and South Korea. Their very existence is a reminder that the regime needs monsters to maintain control.

The plot focuses on three characters whose paths converge in the final part of the film. Sujin, a young government official, is trained to detect and hunt down Omegas hiding among the population. Her loyalty begins to falter when she encounters Mia, a mutant who has managed to survive by amputating her fin and running a mysterious underground fishing shop. This place, a nostalgic recreation of a past when it was still possible to fish in the sea, attracts customers in search of comfort. An unnamed Omega also arrives there, having escaped beyond the walls to deliver to Mia the remains of her deceased father. Between the three, neither an epic nor a heroic tale emerges, but rather a dry, hopeless tragedy, where individuals barely manage to recognize one another amid distrust.

Aesthetically, The Fin unfolds as a hypnotic journey. Park employs color filters ranging from the polluted reds to the grays of totalitarianism, and surprises with the warm blues and yellows of Mia’s hideout, evoking the atmospheres of filmmakers such as Wong Kar-wai or Hou Hsiao-hsien. The contrast between these intimate refuges and the barren exterior intensifies the melancholy of a ruined world. Seokyoung Haam’s music and the carefully crafted sound design reinforce the dreamlike dimension of the work, in which the viewer is caught more by sensory experience than by narrative logic.

Far from being just a futuristic tale, The Fin functions as a political parable about manipulation, otherness, and the repetition of old violences under new masks. Park crafts a bitter fable where physical and emotional pain merge, and where myths—such as the alleged deadly scream of the Omegas—serve more to conceal injustices than to reveal truths. Its strength lies in that mix of beauty and despair, making the film one of the most singular offerings in recent Korean cinema.
