In a bizarre dream, Lin Jing sees monsters descending from the sky, everyone dying a miserable death, herself abandoned by her good friend Li Tianyi, mocked by Zhao Tongtong, and finally swallowed by a monster. Awakening from the dream, she finds herself lying on a deck lounge chair of a cruise ship, with bright sunshine, bustling party, and everything as usual. She tries to recount the impending disaster in her dream, but is treated as a joke by everyone. However, shortly after, the cruise ship's engine indeed malfunctions, running aground on an uncharted desert island on the map. The island has no signal, and its terrain is primitive and enclosed. Lin Jing perceives that the dream is fulfilling itself scene by scene.
