Next Time on Doctor Who…

Martha is strapped to a chair against her will with a shadowy figure and an accompanying male voice saying proudly, "Rose Tyler is dead." The Doctor pulls away from a young woman, distraught about a memory.

The TARDIS doors fly open, and Martha plows through them to hug the Doctor. "Nice to see you again, Mr. Smith!"

The Doctor grins. "And you, Ms. Jones."

An alarm sounds off and the TARDIS shakes, making the Doctor, Rose, and Martha hang on. The Doctor shouts over the noise, "Something is overriding the controls! I can't fight it!"

The Doctor, Rose, and Martha walk along a paved road with buildings so tall that the tops are hidden by clouds and flying vehicles amongst flying cars in the sky.

Rose comments, "Aren't we essentially walking into a trap, Doctor?"

A bunch of soldiers suddenly appear next to the Doctor, Rose, and Martha, training their guns on them.

The Doctor replies, "Nonsense, Rose."

The three travelers hear a voice in a dark room. "I'll give you a chance. Turn around and leave, and I'll let you live."

The Doctor yells to his companions as guns go off, "Run!"

Rose piles desks, chairs, and old office equipment to block a door.

Martha tries pressing buttons in a lift as she screams in defeat, "No! No!"

Rose runs down the stairs chased by a black clad man. She kicks a door, making it slam open, running inside and slamming it behind her.

Martha is grabbed by two similarly dressed men into a lit room.

Rose falls down forward, landing on the floor completely still. The black-clad man touches a strap on his wrist as he announces, "Sir, I have eliminated the blonde."

Martha screams in pain and agony while being tied to a chair and a round suction cup squeezes her head.

The Doctor looks intimidatingly at a black-clad man. "Tell me to my face. What have you done with Rose Tyler?"

Inside a mechanical arch, gasses began to appear to form into some type of solid figure. The Doctor stares terrifyingly at it. "No…"

Series 4 will continue with "Agent T.I.N" next week!
