Publisher's summary
When disaster befalls the TARDIS, its occupants find themselves in a bizarre location, somewhere between space and time.

Desperate survivors hide among ruins, greedy scavenging creatures hunt new prey, and ghosts scream out warnings across time.

All the while, a mysterious woman watches the TARDIS crew, knowing, as sure as tock follows tick, that a terrible fate awaits them...

The Graveyard World (1)
No sooner has the TARDIS flown away from Carthage, the console begins sparking, the ship's power being overridden by something nearby. As more hardware explodes, the Doctor scrambles to course correct, shoving aside his companions' attempt to render aid, but can ultimately do nothing as the TARDIS is drawn to a nearby planet and makes a crash landing.

Coming to, Ian, Barbara and Susan inexplicably find themselves in a ruined wasteland, unable to recall how they exited the TARDIS or what happened to the Doctor. Hearing the sound of the ship's engines however, they run after it, catching a fleeting image of a ghostly TARDIS. Susan explains to her teachers that that was a temporal shift, a version of the TARDIS slightly in the past or the future. Examining their surroundings, the three briefly wonder if the ash might be radioactive fallout before Barbara and Susan point out the oddity of the buildings. A mixture of architectural styles that were all stacked next to each other without any consideration for their neighbours. Before moving off, the three hear an odd ticking sound.

As they continue to walk, the three hear a shout aimed at them before they encounter another temporal shift. Susan elaborates, saying that time travel is different from space travel in that only the past destination is fixed. If a time traveller isn't careful, they can jump time tracks into one of the unfulfilled potentials, leaving them unable to properly synchronise with their destination, at least not right away. And the temporal shifts are the worst possible scenario.

Passing by another building, the three see a group of shadows in panic. Though Susan is confident that the temporal echoes can't see or hear them, Ian points out one that is clearly motioning to them. Perturbed by Susan's claims, the echo vanishes, leaving Ian to comment on how familiar she seemed.

Hearing the TARDIS noise again leads them to the prone form of the Doctor, mourning the loss of his beloved ship, with his last act being to allow them all to escape. Needing time to mourn, the Doctor steps away from the group. Sitting in the ruins, Ian and Barbara come to terms with a scenario they knew was always possible, but never wanted to accept: They are never going home.

Searching for her grandfather, Susan comes across the temporal echo from before, finally conceding that she can see and hear Susan. As Susan vents her worries about the Doctor's mental state to the echo, the Doctor pops up. After freeing himself from Susan's crushing hug, the Doctor examines the echo while Susan hears the ticking sound again. As the two Time Lords take their leave, the echo imparts one word onto Susan: "Xesto".

As the Doctor returns to Ian and Barbara, Susan runs up and imparts the echo's warning before the second echo then appears, revealed as none other than Ian. The future Ian warns the four that they must leave this place. Or else this will be the day that they die.

The Time Ship (2)
As Ian struggles to cope with what they've just seen, Susan confirms that they really was a future Ian. As the Doctor and Barbara ponder the message, Ian irritably points out how useless the warning was. They have no idea if they've to do something or avoid doing it and have no choice but to continue as normal. As the four debate if they're stuck here forever, they notice two figures watching them from afar. Ian and Barbara run after them while the Doctor and Susan try to circle around.

As Horl and Katta run, they find themselves barred on all sides and introduce themselves. Brought to a campfire, Horl and Katta reveal their belief that this planet is the afterlife, specifically Ki-Agrea, their people's version of purgatory. After a discussion on religion, the Doctor points out the stars above them, the formations reminding him of Cleaver's Square, a galaxy "some considerable way" from Mutter's Spiral, but definitely a place that can be reached without dying. After hearing that Horl and Katta arrived in the same manner as them, the Doctor suspects that the planet only affects space-time vessels.

As morning suddenly arrives, Horl and Katta takes the TARDIS crew to see Nocta, the oldest survivor on the world. Arriving at a recreated Temple of Gluttony, the Doctor wonders if the antagonistic environment is a result of the anger of the cephalopod that the ship was built around. As they enter, the echo appears to Susan again, trying to bar her. Once in the ship, the group, without Katta, separates to find Nocta, Susan going with Horl.

As they walk, Susan is assaulted by the telepathic agony that the building is in. Horl tells her of the one advantage of this place, a magic box. Elsewhere, the Doctor, Ian and Barbara find the item in question, a Zero Cabinet, a small pocket out of reality, before they hear the sound again. Finding the source to a weevil-like creature twice their size, they flee.

After pushing open a door, Susan and Horl meet the disagreeable Nocta who believes the others are trying to steal her Zero Cabinet, running down to the lower levels.

As Ian and Barbara try to open a blocked door, the Doctor tells Ian and Barbara to run back the way they came, noting the creature's interest in his time energy. Aware that he can't outrun it, he tells his friends to make for the Zero Cabinet before he is swallowed whole.

Death in Time (3)
As Susan tries to reason with Nocta, who has been using the Zero Cabinet to survive the Purges, Ian and Barbara appear, the creature, which Susan identifies as a Xesto, hot on their heels. Nocta seals herself inside the cabinet forcing everyone else to flee. No sooner have Ian and Barbara broken the news of her grandfather's demise to Susan, the beast devours Katta.

In some "temporal hinterland", the Doctor awakens, surrounded by other versions of himself. The other Doctors believe that, being a figure of great importance, their death is being prevented but can otherwise agree on nothing. A new voice makes herself known, an old woman who laughs that those who talk to themselves are quite mad. Recognising the woman as the echo, the Doctor dismisses her explanations as "pseudo-scientific nonsense".

Resigning herself to a difficult conversation, the woman explains that the Doctor that he hasn't avoided death. He is dead. He was devoured by a Xesto but the nature of the planet has created several equally probable occurrences of that event. And once each echo's time is up, they will vanish and the Doctor will die.

On the planet, Ian and Barbara drop a building on the Xesto before returning to the campfire, being offered Xesto meat, Susan explaining the species. As Horl remembers the Xesto crawling around Nocta's ship, she runs back to warn her, Ian and Barbara following. Explaining that the Xesto "mark" a place that they've fed, they observe dozens of Xesto swarming the ship. Though as Horl explains, that's a small number. When the Purge comes millions of Xesto cover the planet's surface, stripping it back to the rock.

In the hinterland, the woman shows the Doctor how to observe what's happening on the planet, explaining that one loses their grip on time the more they stay on the planet. She herself has been here for centuries and is now begging for death. Still wanting to save his friends, the Doctor asks the woman to show him how to talk to them.

Walking to the campsite, the Doctor worries for what will become of Susan without him to watch over her. The woman, in an insulted tone, is quite confident that the young Time Lady will be fine without him before they arrive. Unable to speak to her, the Doctor asks the woman to tell Susan to seek out the remains of the TARDIS. Narrating her actions, the woman tells the Doctor to focus intently on Susan, on her breathing, her clothes, and even the freckles on her skin "as if they were my own."

Appearing to the sulking Susan again, the woman tells her that there's still a chance to save the Doctor but the Xesto are coming and she must find the TARDIS. When she returns to the hinterland however, the Doctor is on his back, dying faster than either thought.

In the Temple of Gluttony, the Zero Cabinet opens to reveal a smug Nocta, brandishing a gun to keep them away from the Cabinet. Silently fuming at her, Ian threatens that he will one day deal with Nocta. As they walk away, Nocta despairs that her gun is broken.

Back at the campsite, Barbara tries to comfort Susan but the Time Lady insists that she cannot relate. Unable to return home and with the Doctor gone, Susan is now truly alone in the universe.

Leading her companions through the ruins, Susan searches for whatever is left of the TARDIS, Horl wonders why the echo is speaking to Susan before an echo of her and Katta appears. Though Horl wishes to touch her lover, Ian has to hold her back. Two versions of one person touching creates a dangerous energy burst, and that cannot be allowed to happen in this unstable environment. As the echo disappears, Barbara points out the horizon.

The Xesto are ready to swarm.
