Screenwriter's creation
I believe the answer is:
scenario
'screenwriter's creation' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for scenario that I've seen before include "Written outline of a film or play" , "Film/novel plot outline" , "Iron case (anag)" , "expected sequence of events" , "Outline -- setting for a novel" .)
