A group of soldiers flee over mistbound ground, trying to elude an airborne attack. One soldier is knocked to the ground by a nearby explosion, then he picks himself up and watches as the planes fade into the distance. A boy is seen to run through the mist. He runs after the child, shouting to him to stop. As with any battlefield there are minefields and the boiy has run into one. When the solider asks the boy if he has ever seen a handmine, the boy nods but the direction of his gaze makes the soldier realise that not only has he too entered the minefield, but one of the handmines has gripped his ankle. As the boy watches the handmine pulls the solider into the mud, and more handmines appear all around him. Shouting for help, the boy fears that he may be trapped. An object is thrown through the air and falls at his feet. Rescue appears to have arrived...

The Drum: an underwater mining facility near Caithness in Scotland, in the year 2119. The crew of The Drum have located a craft of unknown origin on the lake floor. Visual scans in situ have revealed nothing so the craft has been brought on board. Investigating the craft, Pritchard believes its a spaceship, something which Moran disputes. Pritchard also believes that his company owns all assets discovered and so it belongs to the company. Moran notes some strange lettering on the interior of the craft and asks Lunn for light. After he has had a look at the lettering Moran and the others leave the craft to discuss it further, Pritchard remains behind studying other parts of the interior. As the others talk Pritchard studies a pattern at the front of the craft. He then notices a ghost-like figure next to him which waves its hand over the pattern. This causes a burst of flame from the rear of the craft. Moran pushes Cass out of the way but is caught in the flame and killed. Fleeing the section before it is sealed off, the team argue about the death of Moran...only to notice the ghost of Moran watching them.

Escaping from another sticky situation, the Doctor and Clara take stock: the Doctor has to go outside and wipe his boot in the grass; Clara wonders what will stop the attackers from re-arming themselves. Concerned that perhaps Clara is interpreting the word "POLICE" on the outer shell of the TARDIS too literally, the Doctor remarks that they are time travellers, they tread softly, they do not create ripples. However, a group of Vikings emerge from the darkness and surround them.

Seventeenth century England and the highways are made unsafe by the occasional robbery perpetrated by the masked highwayman known only as "The Knightmare". Mr Fanshawe will not allow either himself or his daughter to be robbed by this lone cavalier. However, The Knightmare is not alone: a sinister figure with glowing eyes lurks in the nearby bushes. Convinced that the Knightmare is in league with the devil, the Fanshawes begin handing over their money and other precious items. The arrival of the Doctor interrupts the robbery: the Knightmare was about to acquire one more item - an amulet. While the Knightmare and the Doctor argue about the contents of a trunk on the back of the coach, the driver urges the horses on, thwarting both of them.

Once upon a time the Doctor placed the Zygons and humans in a position necessitating them to negotiate a peace treaty that would allow the Zygons to remain on Earth. Twenty million Zygons have been rehoused and resettled all around the world, disguised as humans. Both races will maintain the peace treaty unless either a human or a Zygon breaks the ceasefire. To protect against this nightmare scenario, the Doctor left a box with Osgood. Osgood alerts the Doctor that the nightmare scenario has occurred.

Returning to Earth, the Doctor tries to speak to two undercover Zygons who are members of the Zygon high command. He is unable to stop them from being kidnapped: it appears that a faction has arisen within the Zygon community that no longer wishes to remain in hiding among the human race - the ceasefire has ended.

Professor Rasmussen records a message to warn anyone who receives it that they must not watch it! He also warns that once watched you can never unsee it. His message is also comprised of footage, in some kind of order, from recent events that took place on board Le Verrier lab, a space station in orbit around Neptune.

A rescue team from Triton, comprising Commander Nagata, Chopra, Deep-Ando and a grunt designated number 474 arrived on Le Verrier to find out why, 24 hours previously, the station fell silent. They find the lab station deserted, until they encounter two other new arrivals, engineer and stress assessors, called the Doctor and Clara.

After another narrow escape for the Doctor and Clara they collect themselves back on board the TARDIS, but they are interrupted by the TARDIS phone ringing. The caller is Rigsy (Flatline): he has a strange tattoo on the back of his neck and has lost a day of his life. At first neither the Doctor nor Clara are interested - after all, they are not there to help someone out after getting a tattoo on some drunken escapade. However, this particular tattoo is a number and it is counting down. Soon after, the Doctor, Clara and Rigsy start searching for a trap street, a street that is hidden by a misdirection circuit. Only there will they find out who has marked Rigsy for death, and why.

"As you come into this world something else is also born. You begin your life and it begins a journey towards you. It moves slowly, but it never stops. Wherever you go, whatever path you take, it will follow. Never faster, never slower. Always coming. You will run, it will walk. You will rest, it will not. One day, you will linger in the same place too long. You will sit too still or sleep too deep. And when, too late, you rise to go, you will notice a second shadow next to yours. Your life will then be over.

The Doctor arrives at a vast castle, far from anywhere, in a place and a time familiar and yet difficult to locate. His sole companion is a mysterious veiled figure that keeps following him, unchanging in its pace, untiring in its pursuit. It as if he is trapped in his own nightmare for he knows the touch of the Veil will bring death, but there appears to be no other means of escape.

Somewhere in Nevada, USA, the Doctor hitches a lift to a diner. The waitress there asks him what she can get him, but the Doctor admits he has no money...but he can play (raising his guitar). This seems to satisfy the waitress but as he strums a few chords, she asks the Doctor if it is a sad song. "Nothing's day until its over, then everything is" he replies. The title of the tune is Clara: the waitress asks the Doctor to tell the story of Clara.

On Mendorax Dellora, it is Christmas Day, 5343. Nardole is wandering through the streets, evidently struggling with the directions he has been given. Spotting a large blue kiosk, he knocks on the door and after a short discussion with the man who emerges, Nardole asks if he is the surgeon. Since its close enough and there is unlikely to be any singing, the Doctor agrees to go with Nardole. As he tries to find out more about the medical emergency, the Doctor is brought to a flying saucer. The woman who emerges is none other than River Song...but she does not recognise the Doctor! Her main concern is that her husband is dying.
