==== ''The Time of the Ice Box''====
The icy wilderness is revealed to be [[Antarctica]] in the year 1990. Liz and Simon are rescued from the ice and brought to a research base – the International Institute for Biological Research, nicknamed the "Ice Box" - headed by Morgan C. Devereaux ([[John Barron (actor)|John Barron]]). Liz and Simon manage to escape and return to the present time, but only just after Liz believes she has seen her mother in the Ice Box. In the present, Traynor is amazed to learn of Devereaux's presence in the future; he had been a student of Devereaux's and believed he had died in 1969. Using Simon's curiosity about these events, Traynor persuades the children to return to the Ice Box and Liz is stunned when she encounters first her mother, and then her future self – a cold, emotionless, scientist going by the name Beth (Mary Preston) – working in the Ice Box. The staff of the Ice Box are conducting controlled experiments on human volunteers, including tests of a longevity drug called HA57. A catalogue of failures has been plaguing the research effort, but Devereaux refuses to entertain the possibility that the base computer is making errors. The failures get worse, and Devereaux's behaviour becomes more and more erratic. Liz and Simon learn that Devereaux is a [[cloning|clone]] of the original Devereaux, the first in the world. Investigating further, Liz and Simon discover that the purpose of the computer is to create a new clone of Devereaux. This is so that the formula for the longevity drug, which is known only to Devereaux and not written down, can be preserved and kept secret. Liz discovers to her horror and disgust that her father Frank is also in the Ice Box, but has been buried under the ice for ten years as part of an experiment, but the experiment fails when the Ice Box temperature controls fail. The Ice Box researchers confront Devereaux, attempting to convince him that the computer is malfunctioning. Devereaux is unable to accept his failing and, suffering a mental breakdown, escapes out into the Antarctic ice. As the computer fails, the base begins to freeze over. The staff, including Jean and Beth, each take a dose of an anti-freeze formula in the hope of surviving the cold until rescue arrives. Liz and Simon depart; as they approach the Time Barrier, they discover the frozen body of Devereaux.
