Deep beneath the Arctic Ocean, an American submarine is stealthily tracking a U.S. sub in distress when it suddenly disappears. In a direct response, the U.S. Navy dispatches the USS Arkansas under the command of newly-appointed captain Joe Glass to investigate. Unbeknownst to Glass, his vessel is about to enter a covert mission fraught with international stakes and intrigue. As they arrive on the scene, they discover a sunken U.S. submarine damaged in a mysterious way, igniting suspicions of foul play. The crew soon learns of a Russian coup d'état, which has led to the kidnapping of the Russian President by his rogue defense minister.

While Glass and his crew work to navigate the treacherous waters, a covert operation is set in motion on land. A team of Navy SEALs is tasked with a dangerous mission: infiltrate Russian soil, rescue the captured Russian President, and prevent a rising military conspiracy from tipping the balance towards global conflict. As time runs out, Glass must ally with an unproven crew and work alongside the SEALs, executing a synchronized mission to avert a world-wide crisis. The silent underwater chase quickly evolves into a tense geopolitical thriller, where one wrong move can trigger an international incident of catastrophic proportions.
