The top series takes on the theme of forbidden love and crafts it into a modern Romeo and Juliet. However, instead of the Montagues and Capulets, it depicts the lives of a South Korean billionaire and CEO, Yoon Se-Ri, and North Korean Special Forces Unit Captain, Ri Jeong-Hyeok.
Because of the strict division of North and South Korean territory, the pair would never have met under normal circumstances. However, as if brought by destiny, Yoon Se-Ri crashlands in the North Korean Demilitarized Zone after her encounter with a hurricane while paragliding in South Korea. This is where she meets Captain Ri Jeong-Hyeok.
The following episodes unravel two different cultures (North and South), as Captain Ri and his team try to find a way to secretly get Se-Ri back to Korea without any officials finding out. To ensure her safety and to keep her identity hidden, Se-Ri comically finds herself trying to fit in with North Korean life.
