An aging, wealthy man who defected from North Korea and built a $100 million fortune in South Korea realizes his time is running out. By chance, he learns that he had a son he never knew about—only to find out the son has already passed away.

Just as hope seems lost, he discovers that his son had a daughter, also a defector, now living somewhere in South Korea. Determined to pass on his legacy, he sets out to find her.

Amid the search, a touching story unfolds about long-lost family, reconciliation, and a budding romance between a South Korean man and a North Korean woman who must overcome their differences to find love—and a sense of belonging.
