 John Steed works for British Intelligence and always has a female partner. 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 adrenalin 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.
