Being in the wrong scene, exit (9)
I believe the answer is:
existence
'being' is the definition.
(synonyms)
'wrong scene exit' is the wordplay.
'wrong' is an anagram indicator.
'scene'+'exit'='sceneexit'
'sceneexit' anagrammed gives 'EXISTENCE'.
'in the' is the link.
(Other definitions for existence that I've seen before include "Way of life" , "State of being" , "A way of living" , "survival" , "The business of being" .)
