Plot
The independent Earth Colony Axista Four was supposedly founded in the 2439 by Stewart Ransom, a noted humanitarian. Arriving on the colony one hundred years later, the Doctor, Zoe and Jamie find a near-civil war.
'Realists' have abandoned Ransome's 'back to basics' ideals and are raiding the remains of the colony ship to further their technological advancements. The 'Loyalists' are in danger of extinction. In a little-known underground bunker, aliens who claim to be the planet's first colonists are stirring.
Hopeful colonists hope Random's daughter, Kirann, can be revived from cryogenic suspension and reunited the colony. This does not work out as expected.
