On September 14, 2025, a murder occurs on the outskirts of Rivervale.
This draws the attention of FBI agents Jason Starshield and Lydia Crow.
They are pulled into a world where supernatural beings set the agenda.
Rivervale lies near the Canadian border - a city of rivers, rain, and cold.
It is largely populated by Eastern Europeans.
Among its residents are Malcolm Hampton, Emma and Mikael Bathory, and their mother, Regina Bathory.
She is a businesswoman with iron claws.
