What Is Iguana About?

The premise of Iguana in 258 words, with nothing given away. The full story follows below.

In the unforgiving world of a 19th‑century whaling fleet, the sea is as brutal as the men who earn their keep upon its decks. Among the hardened crew, a harpooner known only by his grotesque moniker endures relentless mockery and violence. His face, scarred by strange, hummocky growths, marks him as an outsider, and the cruelty he faces becomes a relentless drumbeat that drives him toward a breaking point.

When the pressure finally shatters his restraint, he flees the ship and drifts to an uncharted isle shrouded in mist and isolation. There, stripped of the hierarchy that once bound him, he claims the barren landscape as his own domain, proclaiming himself ruler of a stark, primitive kingdom. The island’s raw beauty—sharp cliffs, tangled foliage, endless horizon—mirrors his own inner turmoil, turning the wilderness into a crucible for a mind bent on reshaping power on his terms.

The secluded realm soon becomes a silent warning to any soul who might wash ashore. Travelers who are drawn to the remote coast find themselves caught in a tense, almost mythic standoff with a man who has turned his suffering into a relentless, personal crusade against the world that once condemned him. The film drapes its narrative in a bleak, gothic atmosphere, where the relentless howl of the ocean and the oppressive stillness of the island feed a growing sense of dread. In this unforgiving setting, Oberlus—the disfigured harpooner—embodies both victim and tyrant, inviting the audience to wonder how far a fractured humanity might go when pushed to the edge of isolation.

What Happens in Iguana?

The complete story of Iguana, from the first scene to the last, in 359 words (about 2 minutes). Spoilers throughout.

Spoilers ahead

Set at the dawn of the 19th century, Oberlus [Everett McGill], a harpooner on a whaling ship, endures constant ridicule and brutal abuse from his fellow sailors. His right half of the face is grotesquely disfigured by hummocky outgrowths, earning him the nickname Iguana. After a brutal beating, he escapes to Hood Island, an uninhabited refuge. There he is discovered by a team led by captain Gamboa [Fabio Testi], who brutalizes him and binds him for punishment, though Iguana manages to escape and hide in a cave. The ship leaves the island, and Gamboa orders that sailor [Sebastián] [Michael Madsen] be tied to a post on the coast as punishment for letting Iguana escape. Oberlus finds Sebastián and proclaims himself King of Hood Island and Sebastián his first slave, forcing him to cook his meals.

Declaring revenge upon the world, Oberlus enslaves two other sailors thrown ashore after a shipwreck. He keeps his captives in a cave with a disguised entrance. One day, a ship carrying [Carmen] [Maru Valdivielso] and her fiancé [Diego] [Fernando de Juan] moors near the island. Oberlus takes them prisoner. Oberlus kills Diego and makes Carmen his concubine. The ship’s captain, assuming Carmen and Diego to have died in the storm, does not look for them, but sails away.

One day, Oberlus notices the arrival of his former whaling ship. At night, he climbs on board, kills two sailors on the deck, takes Gamboa prisoner, and sets the ship alight, having previously locked the hull. Gamboa fights Oberlus, but is killed by him.

resigned to her fate, Carmen tells Oberlus that she is pregnant with his child. Months later, the captain of the ship Carmen and Diego arrived on, returns with a group of armed sailors. They begin their search and Oberlus has to flee to the other end of the island with pregnant Carmen and his surviving prisoners. Carmen gives birth, but Oberlus takes the child, saying that he will not allow him to suffer as he did, implying that the child is disfigured as he is. With the child in his arms, he enters the sea, intending to drown himself and the child.
