 This closest Flemish equivalent of "Third watch" (but 9 years older) is about the work of a Fire Department in a Belgian town, comprised mainly of volunteers but lead by a professional cadre, the grumpy Adjudant (as in France a rank just under Second Lieutenant) Maurice Haegeman being in daily charge and trying to impose a type of discipline even military professionals wouldn t stomach easily nowadays, under the authority of colonel Walter Halleux who is more concerned with political liaison, budget etc. Naturally the more personal aspects of life in the fire station (bunking, waiting...) and in some cases interwoven private lives also provide story lines, besides the various operations: fire alerts (false and true), kitty in a tree, removing a wasps nest etc.
