sentences:  A scene breakdown (whittled down from six parts to four) was commissioned on 12 July 1983, but after three months of development on the scripts, during which the story was restructured into two 45-minute episodes, it was ultimately rejected.The plot involves the disappearance of various people on Earth, which leads the Doctor and Peri to the planet Hexagora where the Doctor becomes romantically involved with Queen Zafia who is trying to save the insect race of Hexagora from destruction through a plan to infiltrate and take over Earth.It was later adapted as "Hexagora" by Paul Finch for Big Finish's "The Lost Stories" with Tegan and Nyssa in November 2011.
