The plane of a top idol encountered an unpredictable return and was forced to land on an uninhabited island. In this place where fate disappeared, an adventure that could not happen in reality began. Seo Joon-oh (played by Jung Kyung-ho), who was once a talented musician but now has become a lifestyle artist, repeatedly fought a life-and-death struggle with the people who died with him after the plane crash. Seo Joon-oh's new assistant, Luo Fengxi (played by Baek Jin-hee), as a survivor of the crash and an eyewitness to all the events, will become a key figure in promoting the development of the plot, and her testimony is also the only key to finding the whereabouts of the missing.
