Xinyuan Hospital has become a game field of life and death. The smell of disinfectant water is mixed with blood. Lasers, monsters and deadly traps are scattered in every corridor. Lin Zangyue, Jiang Shou, Wen Lan, Ling Che, and Ling Yingran, five strangers were forced to form an alliance due to desperate situations, and became each other's only salvation.
Lin Zangyue, who has the "King" in his neck, Jiang Shou, who uses loyalty as a shield, Wen Lan, who hides the pain of reincarnation, Ling Che, who is a kindhearted doctor, and Ling Yingran, who is pure and tenacious. They have very different personalities, but they fight side by side at critical moments of life and death: some stand in front of them to resist fatal attacks, some rely on medical skills to keep their companions alive, some use wisdom to crack strange rules, and some use courage to dispel the fear in their hearts.
Monsters are transformed by obsessions, and "fear resonance" makes emotions become life-threatening talismans. The so-called exits are all scams. But this friendship tempered in blood has become the strongest armor. They trust each other and support each other. In the struggle and choice of human nature, they use their bonds to fight against the endless darkness. This is a group-like escape from a desperate situation, and it is also a passionate elegiac song about friendship, survival and humanity.
