Commander Koenig and his colleagues speed through space and time into a chilling world of ice - and meet former inhabitants of earth.
The codename given to the planet which has come into view is "The Ice Planet" because of the computer readings that it has atmosphere, but temperatures Moonbase Alpha personnel would find intolerable, dropping at night right down to 200 degrees below. Its gravitational pull is so strong that it is affecting the moon's trajectory.
Then, surprisingly and dramatically, a signal is received. It is a human voice, and it is reporting "We have life here, a long life that you could share ............ Ultima Thule is a lost paradise! Come!"
For Commander Koenig (MARTIN LANDAU), the prospect is so interesting that he decides to investigate. Accompanying him in the reconnaissance Eagle are Dr. Helena Russell (BARBARA BAIN), Professor Bergman (BARRY MORSE) and Alan Carter (NICK TATE) at the controls.
They land. The planet's surface is deep in snow and ice, hidden in an impenetrably thick mist, the wind howling. They are able to identify where the signals are coming from. For a time, they get separated. Carter manages to get back to the Eagle; the others succeed in getting together, fighting what seems to be a losing battle.
The cast of "Death's Other Dominion" includes John Shrapnel, David Eillison and all the regulars of the series, with a great deal of the action centred on Nick Tate
The episode is very much of a husband-and-wife effort. Producers are Gerry and Sylvia Anderson. Stars Martin Landau and Barbara Bain are married. And the screenplay is by husband-and-wife Anthony Terpiloff and Elizabeth Barrows.
