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.
