The Avengers

Enemy agents use a device that transfers their minds into the bodies of Steed and Mrs Peel, effectively commandeering the famed duo. Their subsequent strange behaviour makes them a threat to national security, as the altered agents act unpredictably and endanger state interests.

Who's Who?? is an episode of a television programme that presents a compact, self‑contained story. The title hints at identity confusion, which becomes the central focus of the plot. It follows the familiar world of the series’ lead characters, John Steed and Mrs Peel, while introducing an unusual twist. In this instalment, hostile agents make use of a sophisticated device designed to relocate their minds into other bodies. The technology allows the enemy operatives to hijack the physical forms of Steed and Mrs Peel, effectively taking control of the two agents. The transfer is seamless, and the foreign consciousnesses inhabit the bodies of the well‑known duo without immediate detection. Once the mind‑swap is complete, both Steed and Mrs Peel begin to behave in ways that are strikingly out of character. Their actions become odd and unpredictable, diverging sharply from the mannerisms and attitudes that colleagues and allies normally associate with them. This sudden change in conduct is noticeable to those around them and raises immediate suspicion. The altered behaviour of the two agents is quickly recognised as a serious risk. Their erratic conduct is seen as a potential threat to national security, prompting the intelligence services to treat the situation with utmost urgency. The episode therefore centres on the danger posed when enemy minds occupy the bodies of trusted operatives.
