Scheme set up in the Austrian Alps (4)
I believe the answer is:
plan
'scheme' is the definition.
(thesaurus)
'set up in the austrian alps' is the wordplay.
'set up' is a reversal indicator.
'in' indicates the answer is hidden within the clue.
'nalp' is hidden in the letters of 'austrian alps'.
'nalp' reversed gives 'PLAN'.
(Other definitions for plan that I've seen before include "Programme" , "Schedule" , "Devise a way to achieve" , "Road map" , "Map; intention" .)
