Emma and Julien must do everything they can to stop the next attack. If they can follow the clues, perhaps they can succeed.

The acclaimed series follows retired detective Julien Baptiste (Tchéky Karyo) as he delves into Budapest’s corrupt underworld to find a British Ambassador’s family who go missing on a skiing holiday in the Hungarian mountains. Ambassador Emma Chambers (Fiona Shaw) is thrust into the crosshairs of Baptiste’s most complex case to date, as the detective navigates an untrustworthy Hungarian police force and international media interest as he hunts for her husband and two sons.
