Film story in a score rubbished (8)
I believe the answer is:
scenario
'film story' is the definition.
'scenario' can be an answer for 'story' (thesaurus). I am unsure of the 'film' bit.
'in a score rubbished' is the wordplay.
'rubbished' indicates anagramming the letters.
'in'+'a'+'score'='inascore'
'inascore' with letters rearranged gives 'SCENARIO'.
Can you help me to learn more?
(Other definitions for scenario that I've seen before include "Film script outline" , "Written outline of film, etc" , "Outlines of drama" , "Dramatic situation" , "expected sequence of events" .)
