Publisher's summary
In her bedroom on board the TARDIS, Nyssa dreams of her long lost home, and a Forbidden Archway that never really existed — or did it?

In the TARDIS corridors she finds a flight of steps, a door marked 'keep out', and beyond, a locked room full of secrets. In particular a casket containing a jewel seems to call to her. “Nyssa of Traken, do you want to be my friend?”

So begins a journey that takes Nyssa from snow capped mountains to vast cities, and introduces her to people she seems to know so well. What dangerous landscape has she wondered into — and can she ever escape to safety, and the comfort of her travelling companions?

Plot
Nyssa wakes from another dream of her time on Traken, and the mysterious "forbidden archway" that she keeps seeing in her dreams. Resolving to tell the Doctor about these dreams, she travels to the console room, only to find the Doctor, Tegan, and Adric arguing yet again. Nyssa instead leaves to go be alone, and breaks down into tears in the TARDIS hallway.

Wandering around, Nyssa eventually finds a doorway that is an exact match for the forbidden archway she keeps dreaming of. Ignoring the ornate, "Do Not Enter" sign on the door, she enters the room to find a sort of map room. Examining what appears to be a star chart, she touches one of the stars on there, only for the star chart to show the destruction of that solar system. Horrified, Nyssa backs away, but is startled when a voice begins to call out to her.

Nyssa identifies the source of the voice, a small red jewel located in a box. The voice asks her if she would like to get away from her current situation, and implores her to touch the jewel. Hesitantly, Nyssa touches it and is instantly transported to Arcadia, where she meets an old man, who calls her Susan. Confused, Nyssa insists she is not Susan, until a another man appears, and claims that he can help Nyssa escape her current predicament.

Just as Nyssa is about to help, the old man, now with a younger face implores her not to help. Before Nyssa's eyes, the man transforms into a tall old man with white hair, the first Doctor she ever met, before eventually becoming the Doctor she travels with. All the while, the Doctor implores Nyssa not to give in to the Master, who similarly transforms through different forms, including the face of Nyssa's father, Tremas. As Nyssa struggles with the Master, she sustains a cut to her face and a part of her hair is cut off.

Coming to in the Doctor's TARDIS, Nyssa finds the Doctor, Tegan, and Adric standing over her with worry. The Doctor is angered that Nyssa could give in to such a trick, while Tegan and Adric try to defuse the situation. Relenting, the Doctor explains the origins of the red jewel: that it was a toy gifted to his granddaughter, Susan, by a family friend. The Doctor explains that the jewel is a communication node that acts as a telepathic conduit into an intergalactic transdimensional network. He explains that Susan once used the toy too much, and the Doctor had to hide the toy away. After Tegan and Adric leave, Nyssa asks the Doctor if the family friend was the Master, and the Doctor confirms that. Asking the Doctor if the Master is still alive, the Doctor tells Nyssa that the Master has a nasty habit of surviving. The Doctor then replaces the sign on the window, and heads back to the console room with Nyssa.
