After leading some of his fellow players in an uprising against the games, Seong Gi-hun (Lee Jung-jae) sees his rebellion instantly squashed. The man he thought was an ally in the game was actually the villainous Front Man (Lee Byung-hun),

The second season flashes forward a few years after Seong Gi-hun (Lee Jung-jae), a.k.a. Player 456, won the games. The trauma of everyone's death from Season 1 still weighs heavily on Gi-hun's conscience, causing him to devote himself and the $45.6 billion won (about $31 million dollars) he won to finding and ending the games once and for all.
