Story about one’s guide (5)
I believe the answer is:
pilot
'guide' is the definition.
(pilot can mean a navigator)
'story about one's' is the wordplay.
I cannot really understand how this works, but
'one' could be 'i' (Roman numeral) and 'i' is found in the answer.
'story' could be 'plot' (plot is a kind of story) and 'plot' is found in the remaining letters.
No letters remain.
This may be the basis of the clue (or it may be nonsense).
(Other definitions for pilot that I've seen before include "trial episode" , "Guide - flier" , "Plane flier" , "Ship's guide" , "air traffic controller?" .)
