Fresh out of college, Shen Yan plans a graduation trip before starting his career, but the flight he boards malfunctions over the ocean and plunges into the sea. Most passengers are killed or missing, and only six manage to drift onto a remote, isolated island. With all communication devices destroyed, the outside world has no way of knowing their fate. The survivors are a complicated mix: a calculating middle-aged corporate boss, a fake couple each with their own agenda, a physically and emotionally fragile young woman, and Shen Yan, who possesses a wealth of practical knowledge but lacks social skills. These six, already deeply divided, struggle to survive on an island with scarce resources and danger lurking everywhere.
