A young woman is found shot on the edge of an old quarry. New police chief Michal Trela discovers it is similar to a crime from ten years prior. His police partner Adrianna discovers her husband was having an affair the night of the murder.
Michal and Adrianna confront the quarry owner about how it is his personal assistant was murdered and why he won't delay demolition of murder scene. The mother of the woman murdered 10 years earlier is hiding some secret documents from WWII.
The new priest finds a bundle of notebooks hidden in the catacombs of the church which could explain a connection between the two murders ten years apart.
