Holiday Camp

From the introduction:

The TARDIS has landed in a long dark corridor. Only on a couple of places a bulb gives out a soft dimmed beacon of light. A siren sounds in the distance. As the group moves out of the TARDIS and into the corridor they will be able to see that it seems to be a bit of a service corridor. Leading away from the TARDIS in both directions. As they walk into the corridor a bit from the TARDIS the siren will stop and after them a force field will go up, the corridor will detach itself from the rest of the corridor and as the players look out they see a docking bay from a spaceport as iron doors go shut.
