Hotel Beau Séjour. Kato, covered in blood, wakes up without any recollection of what happened the night before. Moreover, nobody seems to see or hear her. Slowly it sinks in: she's dead. Who did this to her? And how come a handful of people can still see her, as if she's among the living? Why them specifically? In her search to uncover the truth Kato will discover that a lot of secrets lie dormant under the surface of her supposedly peaceful village community.
