The film is set in the early 1980s, during the early days of Norwegian oil exploration in the North Sea. A team of divers is on a mission to lay the foundation for underwater oil pipelines at depths never before attempted. Among them is a dedicated deep-sea diver who is deeply passionate about his profession. He, along with his brother, are pivotal in this high-stakes operation that promises to bring immense fortune and energy independence to Norway. However, the task is fraught with danger, as working at such extreme depths pushes the limits of physical endurance and technology. The pressure, both literal and metaphorical, builds as the crew begins to face unforeseen challenges that test their resilience and determination.

As the mission progresses, it becomes evident that there is more at stake than just national pride and personal achievement. The diver starts to uncover a web of lies and deception that threatens not only the success of the project but also his life and the lives of those around him. Trust becomes a scarce commodity as he delves deeper into a conspiracy that encompasses corporate greed and government complicity. Faced with moral dilemmas and the harsh realities of risking his life for a cause, he must navigate through treacherous waters, both figuratively and literally, to uncover the truth. His journey is not only a test of his professional skill and bravery but also a profound personal quest for integrity and justice in an environment where both are in peril.
