In the North Sea, an oil rig collapse triggers a cataclysmic chain reaction of events. As the oil industry's infrastructure begins to falter, widespread panic ensues, pointing to an environmental disaster of unprecedented scale. Researchers Sofia, a committed and brilliant marine biologist, and her colleague, Arthur, are thrust into the heart of the crisis. Together, they work against the clock to uncover the truth behind the incidents, delving into a labyrinth of corporate secrets and negligence that have laid the groundwork for the impending catastrophe. Their investigation reveals a disturbing pattern of cost-cutting measures that have compromised the safety of the rigs, putting countless lives and the environment in dire peril.

As their quest for answers becomes increasingly perilous, Sofia and Arthur are joined by Stian, a professional diver with intimate knowledge of the deep sea installations. Their paths converge when Stian is charged with the dangerous task of a rescue mission, venturing into the treacherous waters surrounding the damaged rigs. With each dive, he uncovers further evidence that could be key to understanding the broader implications of the disaster. Battling against powerful storms, towering waves, and the constant threat of aftershocks from the initial collapse, the trio must navigate an uncertain path to expose the truth and prevent a full-scale environmental disaster that threatens the entire North Sea and its surrounding regions.
