An ordinary morning, the world seems stuck in its routine. People go about their usual activities: work, school, shopping. But soon, an unsettling feeling spreads through the streets. The individuals around them begin to vanish without a trace. In an instant, millions of people disappear, as if they had never existed. Those left behind, stunned, witness the same phenomenon happening worldwide: their loved ones, neighbors, friends-all gone, leaving an overwhelming emptiness.
When they awaken, some find themselves in a confined, almost clinical environment with five strangers who speak the same language as them. Confused and terrified, they realize their companions are not from their world but are unwilling participants in a macabre game. Each person is forced to make choices imposed by mysterious entities, with no explanation: participate in various trials or die. With every challenge they overcome, they gain a bit more time before being compelled to play again. But every failure claims a life. The entire world seems to have been plunged into this cruel game, with no understanding of who is behind it or why.
