Lawrence Gordon Clark directs this triple bill of BBC adaptations of the ghost stories by M.R. James. In 'Lost Hearts' (1973) young orphan Stephen (Simon Gipps-Kent) goes to stay at the generous Mr. Abney (Joseph O'Connor)'s estate where he is haunted by two children who previously lived in the house. It turns out the children have come to warn Stephen that Abney is not all that he seems. In 'The Ash Tree' (1975) Sir Richard Fell (Edward Petherbridge) inherits his uncle's manor and grounds. He moves in and decides to cut down an ash tree that could prove harmful to the property but before he gets the chance he begins to hear strange sounds and sees supernatural figures coming from the tree... In 'The Treasure of Abbot Thomas' (1974) cynical Reverend Somerton (Michael Bryant) is completely close-minded when it comes to paranormal activity. His steadfast beliefs falter, however, when his and Lord Peter Dattering (Paul Lavers)'s search for the treasure of alchemist Abbot Thomas (John Herrington) unleashes a terrifying spectre.

A collection of classic Doctor Who episodes featuring Tom Baker and Jon Pertwee in the role of the Doctor. In the four-parter 'The Horns of Nimon', the Skonnon ships have returned to the skies of Aneth, demanding tribute. But as the final consignment is being taken to Skonnos, an accident forces the ship off course. In the six-parter 'The Time Monster', a new invention to transport matter through time creates a number of disturbing distortions in the temporal fabric. The Doctor (Jon Pertwee) investigates, and soon finds himself up against his nemesis, The Master, in a battle to control a powerful sacred crystal. In the four-parter 'Underworld', the TARDIS lands the Doctor (Tom Baker) in a Minyan spaceship that is on a quest to find the Minyan race banks stored in a missing ship known as the P7E. They eventually find what they are looking for in a cave system at the centre of a newly-formed planet. But the P7E's computer has ideas of its own, and doesn't look kindly upon its new visitors.
