Sixteen-year-old Ji Yu and Jiang Linyan were involved in a strange S-level dungeon on their way to school, and formed a temporary team with Xie Jinping, He Sichuan, and Chi An. In the confinement activity room, the "shadows" in the darkness are waiting for opportunities, and every rule is a matter of life and death. They must find the key and crack the rules within 120 minutes in order to survive. This is not a game, but a survival trial where life is at stake.
Intent: In a desperate situation, trust and courage are the only salvation; young people grow up in the test of life and death, and use wisdom and cooperation to fight against unknown fears.
