Plunder smuggled wine (7)
I believe the answer is:
ransack
'plunder' is the definition.
(I know that plunder can be written as ransack)
'smuggled wine' is the wordplay.
'smuggled' becomes 'ran' (to run something is to smuggle it).
'wine' becomes 'sack' (sack is a kind of wine).
'ran'+'sack'='RANSACK'
(Other definitions for ransack that I've seen before include "Search, leaving no stone unturned" , "Turn upside down in searching" , "Loot or search thoroughly" , "Go through a place causing damage and stealing things" , "Examine thoroughly" .)
