Synopsis
A quirky spy show of the adventures of eccentrically suave British Agent John Steed and his predominantly female partners. Jonathan Steed - an urbane, proper gentleman spy - teams with various assistants throughout the series' run, including Dr. David Keel, Cathy Gale, Emma Peel and Tara King, to repeatedly save the world from diabolical schemes plotted by equally diabolical evil-doers (among them robots and man-eating monsters).
