Filmed almost entirely on location during the Spring of 1969, this remarkable adaptation of Alan Garner's award-winning novel was a radical production that raised the bar for what viewers could expect from a teenage drama – and which was a significant influence on children's television throughout the 1970s. This extraordinary tale of the supernatural, sexual jealousy and class division broke new ground and is presented here as a brand-new High Definition remaster from original film elements in its original fullscreen aspect ratio.
Alison and her step-brother Roger are on a family holiday at a remote Welsh cottage. She discovers a service of old dinner plates which have a strange floral pattern that turns into owls when traced to paper. But what is the connection between this owl service, the strange gardener, the angry housekeeper and the mysterious local legend? Gradually the uncanny power of the valley takes over and the legend begins to unfold.
