In 2526, 8 Earth paleontologists and geologist were investigating a fossil find in a newly discovered case when 7 of them disappear. The only one who seems to have got out is Professor Kyle. She accompanies Lt. Scott and his troop of soldiers into the unmapped caves to see if they can find her colleagues. What they find however is the Doctor and his traveling companions Nyssa, Adric and Tegan who have also just arrived in the TARDIS. They're near the location where the scientific expedition was attacked and Scott suspects the Doctor. There are others in the in the subterranean structures however. Written by

This story replaced a script called The Enemy Within by Christopher Priest
. story idea dealt with the 'secret' of what actually powered the TARDIS, in this case fear. Somewhere hidden inside the TARDIS was the one being the Doctor feared above all others, and the psychic tension between the two of them produced the energy to move through space and time. The story involved the Doctor having to confront and ultimately defeat this fear and was designed to write out the character of Adric. This was deemed unusable. See more
When the troopers are in the caves, the two dark figures in background walk past (to the right) and one of the troopers stops and turns around. As he does this the shadow of a crewmember can be briefly seen on the left wall. This is not the dark figure's shadow because they have already walked past. See more
[regarding Adric wanting to go home
You do not have the monitor skill Adric! And even if you did, I am not taking you back into E-Space!
Then I'll find someone who will take me!
E-Space is another universe! There isn't a taxi service that goes back and forth!
