The plot or setting (8)
I believe the answer is:
scenario
I believe this clue is a double definition.
'the plot' is the first definition.
(I've seen this before)
'setting' is the second definition.
(I know that scenario is a type of setting)
(Other definitions for scenario that I've seen before include "Dramatic situation" , "Written outline of film, etc" , "Storyline" , "Outline of film, novel, etc" , "Outlines of drama" .)
