During the reign of King Sukjong of Joseon, the Southern Party won the clique struggle, triggering the "Gisi Exchange", which led to the expulsion of Queen Inhyeon Min from the palace and the killing of the entire family of Hongmungwan editor Kim Pengdao (played by Ji Hyun-woo). After that, Kim Pengdao endured humiliation and devoted himself to helping Min restore his position, and secretly monitored the leader of the Southern Party, Right State Councillor Min An. Min An sent assassins to kill Kim Pengdao to silence him. At the critical moment, a spell on Kim Pengdao's body took effect, and he disappeared after the light. It turned out that this spell was originally asked by the geisha Yin Yue (played by Jin Ye-seul) for him to protect himself, but it not only saved his life at the critical moment, but also led him through 300 years of time and space to 2012, where he met the young actress Choi Hee-jin (played by Liu Inna) who played the role of Queen Inhyeon. Using the spell and the mobile phone as the medium, the two fell in love with each other during several times of time and space travel, and they were determined to each other, living a warm and sweet life in modern time and space. But in the original time and space of Jinpeng Road, he still has a mission of swords and shadows to fulfill, and the destined ending in history books to be reversed. Staying in the modern world and spending his life with Hee-jin seems to be just a dream that is too beautiful... In the end, can this love that travels through 300 years of time and space come to fruition?
