Q. The Space Museum
The TARDIS materialises on the planet Xeros, inside a museum created by the Moroks. Inside the exhibts the Doctor, along with his companions, notice many familiar creatures, including Daleks - and also themselves.
During their time in the museum niether the Moroks, not the enslaved Xerons, seem to be able to see the Doctor and his companions. The Doctor surmises that the time shift they experienced upon arrival has caused them to become invisible.
To prevent themselves ending up as exhibits inside the museum the Doctor and his companions must ensure that the future they are witnessing must not happen.
Vicki helps the native Xerons become armed, and they form a rebellion against the Moroks. The Xeron revolution is a success, and the Doctor and his companions go on their way happy that the future has been changed sufficiently.
