Episode list

Mrs. Peel is bequeathed an old house by an uncle Jack, whom she never knew existed. In the event, he did not exist. The house is a former lunatic asylum and it is all a ruse by a vengeful ex-employee of Mrs. Peel's to submit her to mind games which will drive her insane.

The Avengers investigate a series of murders of Corporate men, who have all been bidding on a new circuit element. Each one of them seems to have been killed by a powerful Karate blow, so Mrs. Peel visits a Karate Dojo, Steed's inquiries lead him to United Automation, where ex-Ministry scientist Dr. Armstrong is working on an electronic brain, not to mention cybernetic men.

Steed has been having bad dreams involving Christmas trees and a man dressed as Santa Claus. At a party given by publisher and Dickens fan Brandon Storey, two telepathic spies attempt to read Steed's mind and make sense of the dream. However, the dream is echoed exactly by the events of the party, enabling Steed to spot the villains in advance and identify the dangerous Santa.

A modern day Hellfire Club, led by libertine John Cleverly Cartney, plans to incite chaos by killing three foreign Prime Ministers.

Steed is invited to a party on an aeroplane with six other people who include a matador, a cowboy and a circus strong man. As the pilotless , remote-controlled craft takes off, a voice announces that they are bound for a desert island where one of them will be revealed as a super-killer. Mrs. Peel has to work out how to get to her partner as the bodies start to pile up.

On their way to a closing down party at an air base the Avengers' car crashes when they swerve to avoid hitting a dog. The air base proves to be deserted and Steed is knocked out. When he recovers he is back at the car but minus Mrs. Peel and the party, when he gets there, is in full swing. It would seem that he has gone back an hour in time.

Mrs. Peel drives her childhood friend, Major Croft, to the picture postcard village of Little Storping, where he has just purchased a country home. Unfortunately, the entire population are assassins for hire who lure their victims to the village, kill them, and then claim they have never been there. Croft and his valet are killed to prevent them from exposing the sinister secret - and the captured Mrs. Peel is next on the hit list unless Steed can save her. The assassins have her put in a phone call to her 'husband' - actually to Steed - to leave a false trail. Luckily, he understands her code and arrives to rescue her.

Mad scientist Dr. Krelmar is working on a machine that allows two people to swap minds and enemy agents Basil and Lola intend to use it with the Avengers to get them to destroy their network. Basil exchanges personalities with Steed but Mrs. Peel is suspicious that the man who looks like her partner is acting out of character and has to persuade the real Steed what is going on.

Mrs. Peel is invited to a bridge party at a house on Exmoor but when she arrives she discovers that she has been lured there by a man known as 'The joker'. She had once helped to put him in prison, but he has now escaped and with his two crazy accomplices, subjects Mrs. Peel to a series of lethal tricks and traps until Steed arrives to help her.

When a colleague is found dead in a large London department store Steed and Mrs. Peel go undercover as staff members, exposing a dastardly plot by the wheelchair-bound Horatio Kane to devastate the capital with a huge bomb housed within the store.
