Care is on revised plan (8)
I believe the answer is:
scenario
'plan' is the definition.
(I've seen this before)
'care is on revised' is the wordplay.
'revised' indicates anagramming the letters.
'care'+'is'+'on'='careison'
'careison' is an anagram of 'SCENARIO'.
(Other definitions for scenario that I've seen before include "Suggested plan of action" , "Postulated sequence of events" , "Imagined situation" , "Dramatic situation" , "Event postulation" .)
