John Steed works for British Intelligence and works with various partners, notably: Ian Hendry (series one), Cathy Gale (series two and three), Emma Peel (series four and five), and Tara King (series six). The problems he finds are always a bit odd, just on the edge of science fiction (Cyborg killers, a city built under a disused coal mine, a gang put together for adrenaline junkies, and a killer who uses a concentrated cold virus to kill his victims by having them sneeze to death). Steed is always the ultimate in culture and grace as he saves the world each week.
