The action takes place in the imaginary town of Trumpton, a short distance from the equally imaginary town of Camberwick Green, the focus of the first series in theTrumptonshire Trilogy. Each episode begins with a shot of Trumpton Town Hall Clock: "Telling the time, steadily, sensibly; never too quickly, never too slowly. Telling the time for Trumpton". The townsfolk then appear going about their daily business: the Mayor, Mr Troop the Town Clerk, Chippy Minton the carpenter and his apprentice son Nibbs, Mrs Cobbit the florist, Miss Lovelace the milliner and her trio of pekignese dogs (Mitzi, Daphne and Lulu), and Mr Platt the clockmaker.
Although all of the characters and settings are new, the style of the programme follows the pattern established by Camberwick Green, in which domestic problems are cheerfully resolved by the end of the show, leaving the last minute or so for the Fire Brigade to become the Fire Brigade Band and play the episode out.
The Fire Brigade is perhaps Trumpton's most-recognised feature. Captain Flack's roll call was recited in every episode: "Pugh, Pugh,[The Twins] Barney McGrew, Cuthbert, Dibble, Grub."
They are continually being called out to attend some emergency or other (in many cases to resolve fairly trivial matters), but to Captain Flack's annoyance never an actual fire.
The main reason for this was the impossibility of animating fire, water and smoke.
However after "Right men Action Stations", this doesn't stop the Fire Brigade absent mindedly getting out the fire hose and receiving a rebuke from Captain Flack ("No no! Not the hose!").
Well done Gittuss on your FTF
