William Shatner's A Twist in the Tale - Plot Synopsis: Darkness Visible

Three penniless orphans - Murray (12), Ruth (12) and Dot (10) - are the only children from the Home left unclaimed for the holiday period. Wandering disconsolately in the woods, they discover and rescue a dog caught in a rabbit snare. In return, Vespa leads them to her home, the magical house of Miss Angela Dwelf, charming and eccentric white witch. Angela has been called in by the authorities to control Groby Temporal, who has sent one citizen too many into limbo - into what Groby himself calls "darkness visible". The feud between the two sorcerers’ families is of generations’ standing - ever since Angela’s great-grandfather convicted Groby’s father of black magic, and sentenced him to hang ...
But what is it in the children that Groby instantly recognises? What power do they possess that he fears - Groby Temporal, who fears nothing? Angela is intrigued. Is it that they are three children together, or orphans, or - as Angela suggests - simply that they are so young they have time on their side - a sensitive issue for an erstwhile clockmaker who’s overstayed his welcome by more than a century?

Time for a rescue! By dint of stone-throwing, window-breaking and slingshot-wielding, Ruth and Murray manage to get Dot out of the shack safe and sound ... But Groby switches his attention to Murray himself - and sends him into "darkness visible". He swears Murray is lost to them forever - and he and Angela engage in a shape-changing battle to the death on the sands.

Frantically she resets the clocks so that they are chiming together harmoniously - and in the same way that Angela is weakened by dissension, Groby Temporal is by accord. He falls powerless to his knees - to be banished forever by Angela.
The time of Temporal is over. The beach once more belongs to everyone. And the three orphans have found with Angela Dwelf a home worth fighting for: they are orphans no longer.
