The TARDIS materializes in England in the grip of the Second Ice Age - AD 3000. The travelers seek refuge in a converted Georgian mansion known as Britannicus Base, where senior control technician, Miss Jan Garrett and her staff struggle to control the ice barrier creeping across Britain with an ionizer.  Embedded in the ice, Arden and his team, find a perfectly formed body, which Walters names an Ice Warrior.  The body is in fact Varga, the leader of the Ice Warriors, inhabitants of Mars who visitedEarth during its previous Ice Age in prehistoric times. The revived Ice warrior, Varga knocks out Jamie and kidnaps Victoria before setting free the rest of his crew from the ice. Penley realizes that the Ice Warriors are not concerned with the advancing glaciers as they thrive in extreme cold, so he alters the temperature controls and as the heat increases the Warriors begin to weaken. Learning that Varga plans to conquer the Earth, the Doctor frees Victoria and taking over the base, uses the ionizer at full strength to blow up the warriors' spacecraft and halts the glacier.

Episode 1-6 - In episode 1, the TARDIS materialises on its side, but at the end of the story it dematerialises right side up.
Episode 1 - Clent gets it wrong when explaining how the Ice Age came about. He says that too many plants were destroyed, and as plants produce carbon dioxide, that meant a shortage of CO2 in the atmosphere, hence the Ice Age. However, plants use up CO2, so getting rid of them would raise the temperature (the greenhouse effect).
Episode 4- Another gas-related blunder occurs when it is stated that Mars has an atmosphere mainly composed of nitrogen. In fact, it's 95% carbon dioxide and only 3% nitrogen.
