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.

This classic series follows the adventures of John Steed and Emma Peel, two secret agents whose mission is to face the most mysterious and dangerous situations.
