Arrival on the remote South Atlantic island

In 1914, an unnamed Irish weather observer arrives to work at the island's lighthouse. He meets Gruner, the solitary caretaker who tends a crudely fortified beacon. The isolation and mystery of the place are immediately established.

Discovery of the predecessor's diary

While exploring, the observer finds the predecessor's diary, filled with drawings of strange sea creatures. The diary hints at danger and hints at the island's uncanny wildlife. It plants the seeds of what is to come.

First nighttime assault by sea creatures

At night, the creatures besiege the observer's cabin, testing the lighthouse's defenses. He experiences fear as the strange beings pound at the walls and threaten his isolation. The threat reveals the creatures' persistent, intelligent nature.

Fire destroys the cabin while lighting to repel them

On the next night, he lights a fire to repel the creatures, but the blaze consumes his cabin instead. He escapes or survives, deepening his dependence on Gruner and the looming danger. The incident marks a turning point in his understanding of the island.

Aneris the captive female creature emerges

The observer discovers a female amphibious creature outside. Gruner explains she is tame and will not leave her master, framing Aneris as property rather than a partner. He asserts control over the creature and the man alike.

Friend negotiates to stay in the lighthouse

Friend bribes Gruner so he can remain in the lighthouse, accepting the harsh terms of his stay. He begins a fragile routine of coexistence with the caretaker and the captive creature. The arrangement foreshadows the fragile equilibrium that follows.

Creatures climb the lighthouse; Gruner fights

During a night attack, sea creatures climb the lighthouse as Gruner kills them, while Friend faints from fright. The men survive the onslaught, but the encounter exposes the precariousness of their situation. Aneris's presence adds a layer of complexity to the defense.

Gruner locks Friend outside during a defense

In a subsequent defense, Gruner locks Friend outside on the balcony, effectively leaving him to face the attack alone. Friend survives, covered in creature blood but still alive by morning. The betrayal marks a fracture in their uneasy alliance.

Friend grows affectionate toward Aneris

The two men settle into a routine, and Friend grows increasingly fond of Aneris, treating her with care rather than mere fascination. He believes the nightly attacks are connected to reclaiming Aneris, a theory Gruner dismisses. Aneris becomes a symbol of possible humanity or companionship.

Attempt to signal a ship and the flare struggle

Friend tries to signal a passing ship, hoping to get rescued. Gruner attacks him for control of the flare gun, while Aneris intervenes to protect Friend. Gruner explains his refusal to allow rescue, revealing his own motives.

Plans to leave, rescue prep, and dynamite from the wreck

Friend tells Aneris he wants to leave the island, and they plan to salvage dynamite from a sunken ship offshore. They dive to the wreck and retrieve several boxes of dynamite, though Gruner's hostility continues to simmer. The tension between survival and escape deepens.

Lure and blast: dynamite destroys the sea creatures

Back at the lighthouse, they rig a plan to lure as many creatures as possible and detonate the dynamite. The explosion kills many of the creatures, and Aneris reappears more confident afterward. The victory comes with a cost in their fragile relationship with Gruner.

Aneris and Gruner's past revealed

Gruner reveals that he found Aneris trapped in his net and freed her, hinting at a murky past. Friend discovers a photo of Gruner with a wife and recognizes the same woman in the predecessor's photo, suggesting a shared history and possibly a motive.

Aneris presses for a truce; Gruner's fatal decision

Aneris reappears and seems to seek a truce, but Gruner orders her to return. They argue inside the lighthouse; Gruner fires a flare that kills a child creature. He is finally killed by the waiting mob of sea creatures when he leaves the lighthouse.
