Undercover High School

S01E01 The Emperor's Lost Gold

A failed mission leaves Hae-sung and his unit in deep trouble, threatening to end his career at the NIS. To redeem himself, he’s handed an almost unbelievable task: go undercover at Byeongmun High School, an elite private academy, and retrieve ten tons of gold bars valued at $80 million. With no other options, Hae-sung dons a student uniform and leads his team into the school. What follows is a high-stakes operation where every move could expose them, and the clock is ticking.
