Score in a revamped screenplay (8)
I believe the answer is:
scenario
'screenplay' is the definition.
(I've seen this in another clue)
'score in a revamped' is the wordplay.
'revamped' is an anagram indicator.
'score'+'in'+'a'='scoreina'
'scoreina' is an anagram of 'SCENARIO'.
(Other definitions for scenario that I've seen before include "Written outline of film, etc" , "Imagined situation" , "Iron case (anag)" , "Dramatic situation" , "Written outline of a film or play" .)
