The Taskmaster drags Ardal O'Hanlon, Bridget Christie, Chris Ramsey, Judi Love and Sophie Duker into his lair so that he can pit them against each other and watch excitedly as they lose all dignity while fighting to win his golden-head trophy.

Ardal O'Hanlon makes sheep, Chris Ramsey gets younger, Judi Love becomes a queen, Sophie Duker wets teabags, and Bridget Christie gets lost in a small field.

Bridget Christie shoves a cuddly toy inside a traffic cone, Sophie Duker does a dinosaur impression, Ardal O'Hanlon is defeated by a robot, Chris Ramsey is impressed with a hose, and Judi Love is confident about everything except marbles.

Several members of the cast become baffled by things as apparently simple as a high five and a fish tank. Ardal O'Hanlon discovers that a mallet floats, Bridget Christie has a present for the Taskmaster, and Sophie Duker covers some keys in saliva.

Ardal O'Hanlon straddles a mannequin, Judi Love demands access to a puppy, Sophie Duker asks a very good question, and Chris Ramsey takes a sausage to the nostril. Meanwhile, Greg's tiny secretary Alex Horne shows off his mastery of mimicry.

A sound knowledge of food and drink is required as Ardal O'Hanlon indulges in a plant-based snack, and liquids are poured down a giant tube on Sophie Duker's head. Bridget Christie browns a bun, and Chris Ramsey refuses to consume dried spaghetti.

Greg Davies delivers more rough justice as Ardal O'Hanlon sings about leaning on a fence, Judi Love designs some classy headgear, Bridget Christie uses her phone, and Sophie Duker displays genuinely world-class levels of endurance and fortitude.

The race for glory heats up as we reach the business end of the series. Bridget Christie researches Welsh royalty, and Judi Love pokes a shoe under a curtain.

The furious race to claim Greg Davies' gleaming golden head trophy reaches its glorious climax in the grand final. Sophie Duker uses chopsticks to remove valve caps, and Chris Ramsey raps about aubergines.
