Sarah was in the library of the TARDIS, reading one of the many books that the Doctor kept there. She was absorbed in her reading when the TARDIS landed abruptly making the book fell to the ground. The girl picked up the book and quickly went to the console room to look for the Doctor.
"Doctor! What happened?"
"We've landed, but I don't know where," her friend replied.
"It has been a very violent landing," Sarah said.
"Yes, and we have not landed voluntarily, I assure you."
"Where are we?"
"I don't know; I'm going to investigate. You stay here," said the Doctor as left the TARDIS.
They had landed on a strange and desert gray planet. There was no sign of life, neither plant nor animal. More than a planet it seemed a lifeless rock floating in space. The Doctor was uneasy: his instincts told him that they should leave immediately, and he was right: just he had moved away a couple of meters from the TARDIS the ground began to shake every time with more intensity.
"Doctor what happens?!" Sarah asked leaning out the door.
"Do not go out!" he answered. "Go back inside!"
A strong jolt knocked the TARDIS over. Sarah lost her balance and fell, hitting her head on the floor. The last thing she saw before losing consciousness was the Doctor falling to the ground on that cold gray planet.
