Ja Geum Soon was born in 1930 in North Korea. When the Korean War broke out, she escaped to South Korea and was separated from her husband and child. She dreamed of being reunited with them, so she founded a hotel that would become a metaphorical lighthouse – and bring her lost family back to her. The Nakwon hotel chain became a success because of her hard work and determination.
Ja Geum Soon is nearing the end of her life and dreams of being reunited with her grandson, Im Moon Sung, whom she has never met. Her ever-faithful assistant, Jung Sang Cheol, hatches a plan to bring peace to the old woman before she dies. He will hire an actor to pose as Im Moon Sung and seeks out Yoo Jae Heon, a struggling stage actor who has been playing a North Korean soldier in a theater performance. Jae Heon is hesitant at first but decides to take on the role when he learns that he will be paid handsomely for his efforts. The plan seems to be working until Ja Geum Soon’s health takes a turn for the worse and she is not expected to live much longer. With time running out, can they find Im Moon Sung before it’s too late?
Yoo Jae Heon finds himself in a difficult position when he’s tasked with posing as a defector in order to visit an old woman in the North. However, it quickly becomes clear that he may have bitten off more than he can chew. He also meets Park Se Yeon, Ja Geum Soon’s granddaughter – the woman who is running Nakwon… and has vowed not to allow it to fall into anyone else’s hands!
Jae Heon soon realizes that he’s in over his head, but he’s determined to see his mission through. Se Yeon is a powerful adversary, but Jae Heon is determined to find a way to return to the North. Can he succeed in his mission?
