Eight strangers were invited or accidentally bumped into the "Extreme Horror Playground" for various reasons to experience the latest immersive horror "escape" game. As the door closed, the environment inside the venue suddenly went out of control, real NPCs disappeared, wireless signals were blocked, and various strange phenomena occurred one after another. The protagonists need to work together to find a way out in dark mazes, mutated haunted houses, strange secret rooms and mysterious mysteries. There are jokes and fears, trust and suspicion. Every time a mystery is solved, one step closer to the truth, and everyone gradually grows and transforms. In the end, they faced the mastermind behind the scenes, and each chose a different way to escape. Some characters reached self-reconciliation, and finally the secrets of the playground were revealed in an ultimate "mystery battle royale", and the story came to a successful conclusion.
