Plot
In the 17th century, Lord Marchwood employed Erasmus Darkening, an alien trapped on Earth, to make gold out of base metals. Erasmus was secretly working on a transdimensional accelerator to create a portal to his own galaxy. While Marchwood's children spied on Erasmus, he used the accelerator to trap them between dimensions. Lord Marchwood confronted Erasmus and attacked the machine, causing it to malfunction. To maintain immortality, Erasmus used the energy from people he has trapped over the centuries with his technology.
In the present,
Professor Rivers and her assistant Toby perform a scientific investigation of ghost sightings at Lord Marchwood's manor. They are joined by

Rani. A mysterious poltergeist-like entity begins manipulating objects, including writing the message "get out" on a mirror; this is Lord Marchwood trying to scare everyone off to avoid a similar fate. Erasmus uses the accelerator to take Professor Rivers, though she is yet to be fully absorbed by the manor.
Lord Marchwood slays a creature that came to the manor during one of Erasmus' unsuccessful experiments. Aided by Lord Marchwood's sword as a conductor, Sarah Jane comes up with a plan to stop Erasmus by turning him into electricity. Erasmus is destroyed and Professor Rivers is returned. Sarah Jane destroys Erasmus' machine with the
sonic lipstick. While Erasmus' victims were assumed destroyed as well, Lord Marchwood and his children appear in the window of the manor.
