The game opens with the player's arrival in a series of caves underneath the city of Rhem. A video greeting from another explorer, Kales, explains that the player must find an artifact hidden somewhere within the caverns, take a photograph of it, and bring the photo to Kales's brother Zetais. The player must find the artifact in order to unlock the train and leave Rhem.
