Anna Pihl is a newly trained police officer at Copenhagen Police Station. Here, in one of the most populated and busy police districts in the country, she spends her first day of work – and it turns out to be anything but a boring Monday.

Anna was a police trainee in a provincial area, so she doesn’t know Copenhagen, the many districts of the city or the various population groups, and to make matters worse, Anna has to bring her son, Mikkel, to the station.

Out on her first patrol, Anna gets involved in a case about a restraining order among spouses – and Anna gets into a fight, that sends two men to the ER. Was it Anna’s fault? Did she overreact or was it unavoidable?

The case doesn’t stop there, and soon the new big city cop is involved in more than she ever dreamt of, and the consequences are dire.
