The BBC pulled the series from their schedule for 24 March only following the terrorist attack in Carcassonne and continued on 31 March.
The basis for this series was adapted from a series of conversations between Barfoed and Danish photographer Daniel Rye, who lived as a hostage within the terrorist organisation of Islamic State in Syria for more than a year.
In Germany and the Netherlands, the series is also known as Countdown Copenhagen.
The team responsible for filming the series attended the 67th Berlin International Film Festival, where the series was promoted prior to the broadcast of the first episode.
On 2 April 2017, the series premiered in Denmark on Kanal 5, and was released on DVD in Germany on 19 October 2017.
