About the series
Visitors from the past begin appearing in the modern world. The guests arrive from the Stone Age, the Viking era, and the late 19th century. They don't know how they got here, and have no idea how to get back. Several years after this coexistence began, the Viking Alfhildr joins the police force and, together with a local detective, must find the killer of other arrivals while also uncovering the reason for their appearance.
