Reminder room

The reminder room was a facility aboard a fake spacecraft in the bunker used by Operation Golden Age.

History
In the reminder room, the people — who Sir Charles Grover had duped into believing they were colonists on their way to a new world — watched on a video screen footage about the perils of life on Earth resulting from pollution, war and overcrowding. Mark told Sarah Jane Smith "we all come in here from time to time to be reminded of the purposes of our mission".

After Sarah claimed she had been brought to the spacecraft against her will, Ruth decided that she had to be "re-educated"; and Sarah was locked in the room while the footage played.

Ruth told Mark and Adam if Sarah remained unchanged afterwards, they would have to destroy her. Sarah forced her way past Mark when he opened the door and locked him in, but returned to let him out so she could prove to him that the spacecraft was fake. (TV: Invasion of the Dinosaurs)
