The Owl Service - Season 1 (1969)

Roger develops his photos of the hillside copse - and they seem to reveal a strange silhouetted figure. Meanwhile, Huw Halfbacon is convinced that the three youngsters have become entangled into a re-enactment of old events which previously resulted in tragedy. Nancy also reveals how, had circumstances been different, she would have inherited the house - had her relationship with its former owner (Alison's father's uncle) been allowed to continue.

Despite her mother's warnings to stay away from Gwyn, Alison meets up with him for a romantic walk among the mountain scenery. They meet again later at the house's derelict stable block, where Alison hears strange noises from a locked shed - similar to what she'd previously heard from the loft before discovering the plates. Roger meanwhile becomes even more disheartened, and pleads with his dad for them to cut the holiday short and leave.

After Alison was forced by her father to snub him at the stable block - and following repeated criticism from his mother - Gwyn feels downhearted. His mother threatens to leave the cottage in 48 hours, but Gwyn wants to stay, and feels helpless. He finally confronts Alison to air his feelings, and explain to her how Bertram was killed in the motorcycle accident. Roger interrupts their meeting and taunts Gwyn - hoping to finally drive a wedge between them. Gwyn now feels as if he has nowhere left to go and, in desperation, heads alone for the mountains.

Gwyn is wandering alone in the mountains, happy and singing to himself. Later, Huw finds him, and reveals a secret hollow beneath a tree containing mysterious artifacts. One of these is the brake-blocks from Bertram's motorbike - and Huw finally reveals to Gwyn that he is his real father, and that he sabotaged the bike years ago in a jealous rage when both men were in love with Nancy. Meanwhile, Roger's father suggests they break the lock and see exactly what's behind the outhouse door.

Roger finally breaks in to the old stable, finding a mysterious stuffed owl hidden there in a glass jar surrounded by paper owls - plus Bertram's broken motorbike. He's then set upon by Nancy, who clearly didn't want him to find them. Nancy then keeps to her word, and hurriedly leaves the cottage with Gwyn and their packed cases. Huw gives Alison the old stone owl pendant from the tree hollow as a gift on Gwyn's behalf, but it has a very strange effect on her - as the powers of the valley legend appear to finally possess her.
