Unit One is a thriller series that tells the story of a group of staunch crime experts from the flying squad. We follow their fascinating yet frightening work in the Danish underworld and are thrilled by their commitment and affectionate solidarity and are equally puzzled by the often horrifying, yet true examples of human nature they face in their work.

What happens to the people who have chosen to work in job like this. A member of the flying squad is away from home 230 days a year. Can a marriage and a family cope with that? What kind of qualifications, what kind of team spirit do these people possess since they have one of the highest success rates in the world?

Unit One is based on true criminal cases through the last 10 years.
