Story one acted out (8)
I believe the answer is:
anecdote
'story' is the definition.
(an amusing or interesting story)
'one acted out' is the wordplay.
'out' indicates anagramming the letters (out can mean wrong or inaccurate).
'one'+'acted'='oneacted'
'oneacted' anagrammed gives 'ANECDOTE'.
(Other definitions for anecdote that I've seen before include "Account regarded as unreliable" , "Yarn" , "Brief story" , "Humorous story" , "Short narration" .)
