As international terrorism and organised crime become more and more intertwined, western nations find themselves increasingly threatened by violence and lawlessness on an unimaginable scale. In Denmark, a special unit is set up to fight cross-border crime throughout Scandinavia and to establish operational links with similar teams around the world. 

A hard-hitting series that soars to new heights of psychologically intense crime drama. Dramatically real stories with a chill that lingers longer than a Scandinavian winter.
