On a rainy night, Lin Chen, a fan of the drama, accompanied his sick mother to replay "Squid Game". When deducing the level loopholes, his computer was struck by lightning and exploded, and he actually traveled into a real death game! With chips implanted in their wrists, 201 challengers compete for 40 billion won. If eliminated, they will die. However, the organizer has already modified the rules and added traps, which is far crueler than the drama.
Relying on the familiarity of the plot, Lin Chen solved the crisis many times from the shadow of "One, Two, Three Wooden Man", to the body temperature skills of "Tang Tang", to the life and death game of glass bridge. But the moment he witnessed the blood splattering, he gave up his obsession with "win-win" and vowed to lead everyone out alive - for the sake of his mother's instructions before the hospital bed, and for the concerns of the passers-by.
Nurse Li Yan, veteran Zhang Biao, and engineer Lao Han form the core team. Undercover Jiang Zhien is struggling with his conscience due to his obsession with saving his younger brother, and the selfish Zhao Yu secretly makes a trip. They crack the activity buttons, find hidden marbles, and seize the control center. They not only have to fight against deadly levels, but also expose the betting conspiracy of the global rich behind them.
The mother's text messages on the phone, the surgery fee for Jiang Zhien's brother, and the life and death bond of the team became the glimmer of light in the desperate situation. From a secret room on a desert island to a global live broadcast, Lin Chen leads everyone to break the rule of "the weak and the strong" and use unity and wisdom to fight against capital hunting. Can everyone survive in the end and let the truth be exposed? And the anonymous invitation at the end heralds that a new test of humanity is about to begin...
