In this Flemish detective series, (mainly serious) crimes in an (inner) city precinct (hence the Dutch title) of Antwerp are investigated, usually leading to arrests, especially by cocky, socially inept inspector detective Tom Segers and his female partner; even though the young petty criminal and innocent hustler 'Ruige' (i.e. 'rough') Ronny Nijs often proves must valuable, Tom treats him like shit; the colleagues at the police station, whose own professional and sometimes interwoven personal problems also provide some story lines, from the uniformed cops to the female district commissioner, have to get used to his less then courteous style since he generally gets the job done.
