"Lord Parker's 'Oliday" is the 30th episode of Thunderbirds, a British Supermarionation television series created by Gerry and Sylvia Anderson and filmed by their production company AP Films for ITC Entertainment. Written by Tony Barwick and directed by Brian Burgess, it was first broadcast on 23 October 1966 on ATV London and Anglia Television as the fourth episode of Series 2. The episode had its first UK-wide network broadcast on 8 May 1992 on BBC2.

Set in the 2060s, Thunderbirds follows the missions of International Rescue, a secret organisation which uses technologicallyadvanced rescue vehicles to save human life. The lead characters are exastronaut Jeff Tracy, founder of International Rescue, and his five adult sons, who pilot the organisation's primary vehicles: the Thunderbird machines. In "Lord Parker's 'Oliday", International Rescue agents Lady Penelope and Parker are holidaying in the Mediterranean town of Monte Bianco when a nearby solar power station is damaged in a storm, leaving its collector dish pointing directly at the town. International Rescue must find a way to re-angle the dish before its beam of concentrated solar energy burns through Monte Bianco.

The title's H-dropping on the word "holiday" mimics the character Parker, who speaks in a hypercorrected Cockney accent.

Plot

Lady Penelope and Parker (voiced by Sylvia Anderson and David Graham) leave England for a holiday in the Mediterranean coastal town of Monte Bianco, checking into a hotel run by Mr Faccini. Thanks to the work of Professor Lungren and his assistant Mitchell, the town is set to become the first in the world to be powered entirely by solar energy. Bruno, the hotel's pessimistic steward, fears that this will lead to "great disaster".

Lord Parker's 'Oliday

That night, the hotel guests attend a fancy dress banquet to celebrate the activation of Lungren's mountain-top solar station. A storm rolls in and the station's tower is hit by lightning strikes, cutting power to the town. The tower's dish breaks off and rolls down the mountain, coming to rest pointing directly at Monte Bianco. Later, the storm clears and the hotel guests marvel as the dish reflects the Moon, concentrating its light and casting a silvery glow over the town. Bruno, however, is dreading the sunrise. Penelope thinks she knows why and uses FAB 1's videophone to alert International Rescue, taking the car out to sea on its hydrofoils to avoid radio interference from the nearby mountains. On Tracy Island, scientist Brains (voiced by David Graham) predicts that when the dish begins to reflect sunlight, the energy projected at Monte Bianco will heat the town until it ignites. Jeff (voiced by Peter Dyneley) dispatches Scott (Shane Rimmer), Virgil (Jeremy Wilkin), Alan (Matt Zimmerman) and Brains in Thunderbirds 1 and 2 with orders to avert disaster.

As dawn approaches, Penelope drives to the solar station to check on Lungren and Mitchell. The station's radio has been damaged in the storm, preventing them from calling for outside help. Back at the hotel, Parker has a plan to keep the guests on hand to fight any fires that might break out: posing as an English lord, he uses his pretend authority to gather everyone together for a very special game: "Lord Parker's Bingo".

Using aerial reconnaissance from Scott in Thunderbird 1, Brains suggests attaching a line to the dish from Thunderbird 2 and using the aircraft's thrusters to angle the dish away from the town. Donning a heat suit, Brains is winched down to guide the line into place, but the thrusters fail to move the dish. Brains discovers that the rotation gears are jammed and burns through them with a laser cutter. Seeing the hotel roof beginning to smoulder, Scott activates a device on Thunderbird 1 which fills the air with smoke, blocking out the sun and stopping the flow of reflected solar energy. A second attempt to move the dish is successful, ending with the structure toppling over. Virgil and Alan are dismayed to see a figure that appears to be Brains buried in the wreckage, but it is only Brains' discarded heat suit.

In the closing scene, Penelope and Parker – the latter now finished playing a lord – resume their holiday.
