In the cold, rolling expanse of the West of Ireland, a modest trawler sets out into waters that are both familiar and forbidden. The vessel is more than a fishing boat—it is a floating community, a place where routine and superstition mingle with the relentless rhythm of the sea. Beneath the gull‑filled sky, the crew contends with the weight of their own histories: a grieving couple bound by loss, a seasoned engineer who keeps the engine humming, and a handful of hands accustomed to the hard, salty work of a life at sea. The film’s tone is steeped in quiet dread, letting the endless horizon amplify the claustrophobia that builds below deck.

When Siobhan, a PhD student obsessed with the hidden patterns of deep‑sea life, secures a spot on the journey, she brings a blend of scientific curiosity and uneasy optimism. Her presence introduces a fresh perspective that collides with the practical, often superstitious mindset of the veteran crew. Freya and Gerard, still haunted by the memory of their missing daughter, navigate leadership and personal sorrow in equal measure, while Omid tends to the mechanical heart of the ship, quietly observing the subtle tensions that surface among his mates. The younger members—Johnny, Ciara, and Sudi—infuse the day‑to‑day grind with a mixture of rivalry, camaraderie, and unspoken longing, each shaping the social fabric of the cramped quarters.

As the trawler drifts farther from shore, a subtle, unseen threat begins to seep into the routine. The crew’s reliance on the sea’s bounty and their own resourcefulness is tested by an unsettling shift in their water supply, hinting at a parasitic presence that defies easy explanation. The atmosphere tightens around them, a blend of scientific intrigue and primal fear, as the characters must confront the growing uncertainty that lurks just beneath the surface of their world. This careful balance of atmospheric suspense and character‑driven drama promises a voyage where every ripple may conceal something far more unsettling than a simple catch.
