On a cold and tense morning at sea, the commander of a United States Navy ship, Captain Eric Finlander, is in charge of a modern missile destroyer. His mission: to patrol the frigid waters of the North Atlantic, a strategic route in the context of the Cold War. Everything seems to be going normally until signs of a Soviet submarine emerge, moving too close to the exclusion zone. Finlander, obsessed with his duty and compliance with international law, decides it’s time to show strength. However, things become complicated when a young correspondent, a cynical and skeptical journalist, joins the crew, seeking a good story about life at sea.
As tension escalates, the captain finds himself consumed by his desire to prove his worth, leading him on a dangerous and risky hunt for the enemy submarine. His impulsive decisions not only endanger the lives of his crew but also have the potential to trigger a conflict of unimaginable proportions. The mission turns into a race against time and logic, where the pressure of duty clashes with the moral dilemmas of conflict and loyalty. In a charged atmosphere, questions arise regarding the price of war and the human instinct for survival.
