The Owl Service was first broadcast during the UK winter of 1969-1970 and features the confusing tale of three teenagers on holiday in rural Wales. They get embroiled in a local legend involving a lady made of flowers, an ancient standing stone, and a tea service with an image of what looks like owls on them.
The legend is brought to life as the teenagers explore their holiday home and meet mysterious local gardener Huw, who seems to talk in riddles.
