When Player 321, a woman with crippling debts and a checkered past, wins the Games in 2016, she is overcome with the grief and trauma brought on by being the sole Winner. 321 devotes her life to finding answers and attempting to take down the Games, even at risk to herself; by any means necessary.
By chance, she stumbles upon Seong Gi-hun in 2022, similarly haunted by his past playing the Games. The two form an alliance, teaming up and using their shared knowledge of the Games and equal desire for revenge to stop the system for good. They eventually grow close, bonding over their mutual trauma.
Everything changes, however, when they do manage to re-enter the Games, and they quickly realize that taking them down might be more difficult than they first believed.
