(Full Synopsis)

Set across South Korea and North Korea, the musical unfolds after an unexpected accident forces two individuals from opposing sides of the Korean peninsula into each other’s lives.

Yoon Se-ri, a successful South Korean businesswoman and chaebol heiress, is caught in a paragliding accident and crash-lands in North Korea. She is discovered by Ri Jeong-hyuk, a disciplined North Korean officer, who decides to hide her and help her return home.

As Se-ri lives under concealment in the North, she encounters the daily lives of North Korean citizens and gradually forms close relationships with Jeong-hyuk and his unit. Their efforts to secretly send her back repeatedly fail, while surveillance by State Security officer Cho Cheol-gang intensifies the danger surrounding them.

Complications arise with the presence of Seo Dan, Jeong-hyuk’s arranged fiancée, and Goo Seung-jun, Se-ri’s former fiancé who is also hiding in North Korea under a false identity.

As Se-ri and Jeong-hyuk grow closer, their relationship deepens into love despite the political and physical barriers between them. Ultimately, the story centers on whether Se-ri can safely return to South Korea and whether their love can endure separation shaped by national division and fate.
