Driven by the promise of quick wealth, the impoverished and desperate Gi-hun accepts an invitation to participate in a mysterious game. Before long, the initial rounds reveal a series of unexpected and horrifying events.

Faced with the choice of continuing or abandoning their endeavor, the group takes a vote. Yet, the harsh realities awaiting them beyond the game's confines may prove no less relentless.

The remaining contenders advance to the next stage, where equal measures of delight and peril await, each harboring secret strengths. Unseen, however, Jun-ho finds a way to infiltrate the proceedings.

With factions solidifying, safety within the dormitory dissolves after darkness falls. The third game demands that Gi-hun’s team consider their moves with careful deliberation.

Night watch was a shared burden for Gi-hun and his team, each taking turns to stand guard. Meanwhile, the masked figures found themselves embroiled in complications with their fellow conspirators.

For the fourth game, the players now form duos. Gi-hun wrestles with a difficult moral question, while Sang-woo prioritizes his own survival. Sae-byeok, in turn, reveals a piece of her hidden past.

The Masked Leader extended a private invitation to esteemed guests, granting them a privileged view of the performance. During the fifth match, however, the strain of competition began to take its toll on several participants.

As the final contenders approach the culmination, a palpable sense of distrust and revulsion permeates their ranks. Jun-ho, driven by a resolve to unearth the game’s hidden corruption, makes a desperate flight.

The final round offers yet another harsh trial, but this time, the outcome hinges on a single participant. The game's architect emerges from obscurity.
