Strangers appear and disappear.
Like deities, they bring wonder into this world—and soon they leave, continuing a journey that no one knows anything about.
Marta doesn’t remember when or why she became a stranger. Hoping to recover the memories she lost, she joins a small agency and meets other strangers, but quickly learns: they are forbidden to talk about the past.
As she comes to grips with a new world for herself and gathers her memory piece by piece, Marta begins to understand that behind the strangers and their mission there lies a multitude of mysteries.
So who are they really? And what reward awaits them at the end of their journey?
