On a planet, covered in ice, a wheezing, groaning sound began and a blue box appeared. The door opened and a tall man with close-cropped hair and a leather jacket stepped out and looked round him, seemingly fine despite the cold weather. He took the deep breath of the air and breathed out. Then he walked along, the ground crunching beneath his feet. In the sky, two stars, one red, one yellow were setting. The Doctor smiled. "What a lovely view" he said and smiled. "Fantastic!" As he continued walking forward he saw something on fire drop from the sky. "Seems like there's fire wherever I go" he said, and ran over.
Less than a kilometre away a ship lay in ruins. From the ship came two men and a woman, each taller than the Doctor, and in ragged remains of uniform. "Co-Navigator and Weapons Officer dead" said the oldest of them. "What happened to us?" "We seemed to have encountered some sort of force barrier" said the Woman. "Navigator!" The youngest of them turned to her, though held his head as blood seeped down. The Woman was about to say something but stopped. "Science Officer!" she said. "Yes Captain!" said the man. "See if you can send a signal" she said. "We need to let Command know of this force barrier. Perhaps that destroyed all the previous exhibitions." The Science Officer began work on the transmitter. "Thank the Power that it survived the crash!" he said. "Oh." "What?" said the Captain. "Communication won't get through" said the Science Officer. "Something's blocking it." "The barrier!" cried the Captain. "That could be it" said the Science Officer. "For the time-being it seems we're stuck here."
"Wait!" said the Captain. She had seen someone running towards them "Should we shoot?" said the Navigator, taking out his gun. "No! But keep your gun ready" said the Captain. The man got to them and gave a broad smile. "Hello, I'm the Doctor!" he said. "Doctor Who?" said the Captain. "Just, the Doctor" said the Doctor. The Captain looked him over. "Are you a native of this world?" she asked. "No. Why would I want to live in somewhere so cold? I just arrived" said the Doctor. "Where is your craft?" said the Captain. "Just over there" said the Doctor. "But I think it's smaller then you'd expect." "Show us where it is anyway" said the Captain. "I don't think I can go on" said the Navigation Officer. "Stay here to guard him" said the Captain to the Science Officer. "I will go with this man."
They walked towards the TARDIS. "Why have you come here?" said the Captain. "Sorry, didn't catch your name" said the Doctor. "Captain Henrietta Io Molkon from Procyon" said Molkon. "From the 18th Scientific Investigation Division of the 10th Galaxy." "I didn't ask for your address!" said the Doctor. "I'm just the Doctor. No fixed abode. Why are you here?" "About a month ago this planet suddenly appeared in this system. There have been multiple investigations but all the previous ships that have come to this planet have vanished. People call this place Puzzle." "This place sounds a bit grim" said the Doctor. "I was sent to investigate" continued the Captain. "But my ship crashed due to some barrier round this world and we can't communicate."
They got to the TARDIS. "Well, here it is" said the Doctor. The Captain looked over the TARDIS. "Trans-dimensional engineering" she said. "I was never able to understand it myself." "I doubt there are many humans who understand it" said the Doctor. "But my people had mastered it hundreds of millennia before I was even born." The Captain tapped the TARDIS. "Open it!" she said. "I need to send a message to the 10th Galaxy Investigation Division immediately!" There was a beeping on her wrist and a red light shone. She looked down. "What is it?" she said. "Terrible Danger! We are being attacked…" Then it cut off. Molkon ran back to the ship, followed by the Doctor.
The ship was lying before them. Molkon looked up. "Any idea what could have done this?" she asked the Doctor suspiciously. "Well, there are a lot of things that could have gone wrong" said the Doctor. "You never know what you could meet on an unknown planet." He looked round the ship. "Is there a black box recorder?" he said. "Of course!" said Molkon. The Doctor smiled. "I would have expected someone of this era to work that out!" Molkon began to use the black box. On the screen an image of the crash appeared. She continued to move through to the images while the Doctor stood behind her, arms clasped and looking round. Suddenly he saw something glint in the half-light of the world. "Molkon, you might want to look behind you" he said, as the glint happened closer. "Not yet, I'm at the point where we left!" said Molkon. The Doctor saw a bright blur move towards them. "Molkon!" he cried. "Turn round now you stupid ape!" "I will in a moment! There's something on the screen!" Next to them the blur stopped. "I can see what took them!" "I know what it is" said the Doctor, looking into the expressionless face before him. "Cybermen!"
