A unique blend of cliquishness, carnival and corruption, Cologne is an ideal turf for a team of expert police investigators. Run in a resolute yet light-handed style by Inspector Karin Reuter, this special squad ferrets out the criminals of the Rhenish metropolis wherever they're hiding. Joining experienced teammate Frank, who's gotten more than his share of bruises on the job, and the always reliable Vanessa are easy-going sportswoman Julia, and brainy, sharp-witted Daniel.
