Alice in Borderland Season 1 Episode 1 Plot Summary and Synopsis
In Tokyo, video-game obsessed Arisu hangs out with his friends Chōta and Karube. While dancing in the streets of Shibuya Crossing, the trio causes an altercation which results in them being chased by the police. Hiding in a bathroom in the station, the group reemerge to find the city completely empty.
At night, the group notices a billboard leading them to a “game arena”. Inside, the trio finds a stack of phones, which show them the game’s difficulty level, illustrated by a playing card. The group is also joined by a highschool girl and another woman named Shibuki who informs them that once a player enters an arena they can’t leave, as a laser would shoot them dead if they tried.
In their first game, a “Three of Clubs” difficulty-level titled “Dead or Alive”, the group is forced to pick between two doors under a certain time-limit, one containing an entrance to another room with the same choice, and the other, certain death. In the end, only the original trio and Shibuki make it out alive, with Chōta leaving with an injured leg.
