Five people encounter a catacomb and take the tour. After they become lost, they find they are trapped, and they see The Crypt Keeper (Sir Ralph Richardson). He asks them each to see why they're there: (1) And All Through the House: on Christmas Eve, Joanne Clayton (Joan Collins) kills her husband (Martin Boddey), expecting to receive his insurance. She hears on the wireless that the police are seeking an escaped homicidal maniac posing as Santa. When the man knocks on her door, she can't phone the police, and she receives a Christmas surprise. (2) Reflection of Death: Carl Maitland (Ian Hendry) leaves his wife (Susan Denny) and children for his mistress, but something happens during his journey. (3) Poetic Justice: the widowed janitor, Arthur Edward Grimsdyke (Peter Cushing), is a good man who spends his leisure time with the children from the neighborhood. His heartless neighbor doesn't like him and destroys his life, leading Grimsdyke to commit suicide on Valentine's Day. A year later, Grimsdyke rises from his tomb seeking revenge. (4) Wish You Were Here: dirty businessman Ralph Jason (Richard Greene) is bankrupt, and his lawyer and friend, Charles Gregory (Roy Dotrice), tells him he must sell his real estate. When he tells his wife Enid (Barbara Murray), she recalls they have a statue with a legend; it'll grant three wishes to the owner. She makes the wishes, and leads Ralph to eternal damnation. (5) Blind Alleys: cruel Major Rogers (Nigel Patrick) comes to the Elmridge home for the blind, with his dog, to be the new director. He tortures the internees until the day they get revenge. Soon, the catacomb visitors discover they are at the gate of Hell.
