In the freezing expanse of the North Sea, the crew of a crumbling vessel faces a double-edged nightmare: a failing hull and a relentless, high-tech hunter. Pietro, Lena, and Mick are trapped in a deadly game of survival when a clinical American voice demands a high-value drive. As a young girl's haunting rhythmic counting echoes through the ship, Pietro makes a desperate choice to hide the asset on her, turning the child into the ultimate target. With a massive, submerged threat closing in, the team must navigate a claustrophobic maze of dark secrets and failing machinery before the ocean—or their pursuers—swallow them whole.
