However, as the train departs, it becomes clear that this is no ordinary journey. The passengers soon discover that the train is a deadly game, orchestrated by an unseen force, where survival depends on solving intricate puzzles and overcoming life-threatening challenges.

The train itself is a labyrinthine structure, with each carriage presenting unique and increasingly dangerous obstacles.
