Bring back right to planned rest cure (9)
I believe the answer is:
resurrect
'bring back' is the definition.
(I've seen this before)
'right to planned rest cure' is the wordplay.
'right' becomes 'r' (common abbreviation).
'to planned' indicates an anagram (I've seen this in other clues).
'rest'+'cure'='restcure'
'restcure' with letters rearranged gives 'esurrect'.
'r'+'esurrect'='RESURRECT'
(Other definitions for resurrect that I've seen before include "Restore to life" , "Revive (something)" , "Revive; disinter" , "Bring back to life" , "Cause to become alive again" .)
