In the cold, relentless expanse of the Atlantic, a determined PhD candidate in marine biology sets out to turn classroom theory into living experience. Siobhan volunteers for a research voyage aboard the weathered trawler Niamh Cinn Óir, hoping the rolling deck and the deep‑water horizon will reveal the secrets of the creatures she studies. The ship itself, a scarred veteran of countless hauls, drifts far from shore, its metal hull humming with the rhythm of the sea—an isolated world where the line between scientific curiosity and survival blurs with each passing wave.
The crew that greets her is a tight‑knit band of seasoned sailors, each carrying the weight of their own histories. Freya, the stoic captain, commands with a blend of authority and quiet grief, while her husband Gerard balances practicality with a restless drive to prove his worth. Omid, the ship’s engineer, tends to the vessel’s aging systems with a pragmatic eye and a wry sense of humor. Their skepticism toward the newcomer is palpable, their wary glances reflecting a culture that prizes experience over theory. Yet beneath the surface of their guarded interactions lies a subtle current of respect, hinting that cooperation may become their only anchor.
As the trawler pushes deeper into unfamiliar waters, an inexplicable and unsettling phenomenon begins to linger in the air and water—a faint, eerie glow that seems to pulse with a mind of its own. The crew’s routine is gradually unsettled by a strange malaise that spreads quietly, turning ordinary tasks into tense, whispered conversations. In this tightening grip of mystery, Siobhan must confront her own doubts and learn to bridge the gulf between academic rigor and the hard‑won intuition of the sailors. The atmosphere tightens, the ocean’s depths echo with the promise of hidden truths, and the fragile alliance forming on deck may be the key to deciphering the looming threat that threatens both the vessel and its inhabitants.
