The game's setting takes place on a spaceship in an era where space exploration is at odds with a deadly parasitic disease called gnosia, which seeks to rid humanity by possessing its host. The player takes control of an amnesiac who either chooses to investigate potentially infected crewmates or become one of the infected. At the same time, the player also tries to end a time loop by harnessing the "silver key" inside of them to acquire enough knowledge needed to end it.
