Publisher's summary
The Doctor is still being jolted through his own timeline, and has now found himself with Nyssa, Tegan and Adric in ninth century Iceland near a Viking settlement on the edge of a volcano. A settlement whose leader has just found a god in the ice.

The TARDIS crew are soon in a battle with the fearsome Ice Warriors. There are a lot of lives to save…and not just those of their new friends.

The Doctor's about to find that his biggest battle may be with his own conscience.

Part one
The Doctor is temporally dislocated to 9th century Iceland, not long after he, Adric, Nyssa and Tegan left Deva Loka, and sees Viking women making a procession to an Ice Warrior. He sends Nyssa and Tegan to join the women to investigate and goes with Adric to speak with the Ice Warrior, apologising to his youngest companion on the way for being hard on him and telling him about the dislocation, which is to be kept secret from Nyssa and Tegan to maintain the timeline. They meet Grand Marshall Xasslyr, whose weapon short-circuits when he tries to use it on them, and they move him into the TARDIS.

Nyssa and Tegan are welcomed by Revna Ulfsdottir after Tegan plays along and pretends to be a beaten wife, sent here on a ship with her sister after being outed as an adulteress. In the night, they overhear Revna argue with her daughter, Inga, and Adric visits them to bring Nyssa back to the ship to give Xasslyr, who is missing a hand, medical care. Xasslyr explains that his spaceship crashed here and that his crew, for whom the women are digging on his orders, is beneath the ice. Upon learning that Mars is dead and that his people are elsewhere, he returns to the caves and orders his newly-located crew to kill the women as their first step in conquering Earth.

Part two
The Ice Warriors kill all of the women but Inga, whom Tegan gets to safety inside the Martian spaceship, and the Doctor, Adric and Nyssa arrive just before Revna succumbs to her wounds. Respecting Adric's choice, the Doctor allows him to go in search of Tegan and heads back to the TARDIS with Nyssa to boil a lake at the top of the volcano, raising the temperature and keeping the Ice Warriors from properly functioning. Adric finds Tegan and Inga in the ship and takes off as the Ice Warriors fire their weapons at it, leading the Doctor and Nyssa to hurry up the volcano as the ship crashes.

Xasslyr takes Nyssa hostage and forces her to hand over her tincture, the purpose of which the Doctor confesses before claiming that it would best be disposed of in an expanse of cold. Xasslyr pours it into the lake, disorientating all of the Ice Warriors and causing an eruption which encases everything in lava. The Doctor and Nyssa run to the TARDIS and are soon joined by Adric, Tegan and Inga, whom Adric wishes to remain on Earth with before accepting that he could not live without advanced technology. Using his torch, the Doctor attracts the attention of a ship to rescue Inga and slips through time once again as Adric and Nyssa build a fire.
