The Turn of the Screw: In Benjamin Britten's operatic adaptation of Henry James' masterwork, a naive governess (Helen Field) arrives at a country manor and soon discovers that it holds a murky secret involving her charges and two ghostly servants who wield a sinister influence on them. The taut, atmospheric production also stars Sam Linay, Machiko Obata, Menai Davies and Phyllis Cannan, with the Stuttgart Radio Symphony Orchestra providing accompaniment.
