A murder in Bolzano mimics a past crime. Assistant Prosecutor Eva Kofler thinks she’s caught the killer, but it turns out to be a discredited inspector who can’t let go of the case. They team up.

Despite their differences in character, Kofler and Costa understand that they must team up to solve the case, even if the investigation puts a strain on Paolo's love life.

A murder complicates the case of a stolen Egon Schiele painting. Could a bombing from 1968 hold the key to help Eva and Paolo solve the crime?

The discovery of the body of the owner of the stolen painting complicates Mathilde's situation. Searching the archives, Eva and Paolo find a lead that could lead them to the Monster.

The Monster case is put on hold when Paolo and Eva are suddenly assigned to another investigation. As their personal lives unravel, will they fight for themselves - or for each other?

Back to investigating the Monster, Eva and Paolo, closer than ever, put all the pieces together and begin to suspect that someone very close to them is hiding behind the killer.
