Some of them are deathly ill, some are in danger of losing their family’s home, while main character Seong Gi-hun is attempting to gain custody of his daughter before she leaves for the United States. The participants are drugged and taken to a secret location to compete against each other in challenges that are based on popular childhood games. Things take a dark turn when they learn that the consequence for losing any of the games is death or “elimination,” as they call it. The winning prize is valued at 100,000,000 Korean won for each participant and 45.6 billion Korean won in total, which is currently valued at around $38.6 million.
