How do people respond when they are called to account for violations? How do enforcers experience this and what does their working day actually look like? In the reality series De Handhavers! the camera follows their work on the street and in public. In the series, several duo's enforcers are followed, who in their work face both funny, sad and violent situations. During their work they regularly end up in high-growth discussions and are confronted with aggression and misunderstanding. The camera also follows enforcers in public transport. In Amsterdam (GVB) and Rotterdam (RET) we see how they act against black-wheelers, youngsters, tramps and nuisance in for example the bus, tram or metro. Finally, we also look at the ProRail employees. They check at level crossings and rely on reports from rail runners or other calamities on and around the track.
