S1E1: Red Light, Green Light

In the first episode of "Squid Game," we meet Seong Gi-hun, a down-and-out chauffeur with a gambling addiction and mounting debts. After a series of unfortunate events on his daughter’s birthday, he’s approached by a mysterious man in the subway who offers him a chance to play games for money. Desperate and intrigued, Gi-hun takes the offer. Gi-hun, along with 455 other contestants, wakes up in a strange dormitory. They're informed they will compete in a series of children's games for a tempting cash prize, but there's a dark twist: losing means elimination, in the deadliest sense. The first game is "Red Light, Green Light," where they must move towards the finish line when the doll calls "Green Light" and freeze when it says "Red Light." As the game begins, one player makes the fatal mistake of moving during "Red Light" and is shot dead on the spot. Chaos erupts as players realize the stakes are life and death. Amidst panic and mayhem, Gi-hun narrowly survives by following the rules and making it to safety just before time runs out, witnessing firsthand the brutality of what he’s signed up for.
