In 1592, during the early days of the Imjin War, Admiral Yi Sun-sin of the Joseon fleet devises a decisive naval strategy to overturn the enemy’s maritime superiority with his brilliant tactics and insight. Opposing him is Wakisaka Yasuharu, one of the main fleet commanders of the Japanese navy, determined to dominate Joseon through an overwhelming seaborne offensive.
The two forces clash in the Battle of Hansando, one of the most pivotal naval battles in Korean history. Through meticulous strategy and calm judgment, Admiral Yi outmaneuvers the Japanese fleet, leading Joseon to a resounding victory. This triumph not only secures control over the seas for Joseon but also marks a crucial turning point in the course of the Imjin War.
