Set in the 21st century, NIGHTFLYERS concerns an old spaceship that is haunted by an evil force. The somewhat decrepit ship is leased by a team of scientists who are launching a search for evidence of a fabled race of aliens known as the Voleryn. The ship's captain, Royd (Michael Praed), is only seen as a computer-generated hologram. Miranda (Catherine Mary Stewart), the team coordinator, falls in love with Royd's ghostly image and he with her. Derivative and predictable, NIGHTFLYERS does benefit from a fine performance by Stewart.
