Season 17 Launch Trailer (TV story)

The Season 17 Launch Trailer was a promotional mini-episode of Doctor Who, billed as a trailer by the BBC, featuring Tom Baker as the Fourth Doctor. It was broadcast on BBC One in 1979.

This mini-episode served as a prequel to Destiny of the Daleks, with a mysterious voice forewarning the Doctor of the coming danger, although to retain continuity with the story it promoted, the Doctor's mind was wiped immediately after, leaving only a subconscious memory.

Synopsis
to be added

Plot
On a planet, a detached voice tells the Doctor to awake several times. The Doctor steps out of the TARDIS, asking the voice why he's been woken up in the middle of August.

The voice warns the Doctor that he will be pitted against an evil force, quickly clarifying it to be the Daleks. The Doctor responds "Never heard of them", before suddenly snapping to attention. He asks when he will face the Daleks, and what they are doing. The voice says it cannot tell him, causing the Doctor to retort "Then why bring it up in the first place?" The voice says "Forewarned is forearmed", and then orders that the Doctor now forget their conversation.

The Doctor, now somewhat confused, asks if someone else is there. The voice begins laughing, and the Doctor joins in as well. The Doctor says loudly "Noisy Universe!" and remarks that a fellow should be able to get a few months' rest. He returns to the TARDIS and turns over a sign on the police box doors, which reads DO NOT DISTURB UNTIL SEPTEMBER 1. The TARDIS dematerialises.
