Pago Pago setting (5)
I believe the answer is:
samoa
'pago pago setting' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for samoa that I've seen before include "Group of Polynesian 14s" , "Pacific island nation, capital Apia" , "island territory" , "Southwest Pacific island group" , "Group of volcanic islands in the S Pacific" .)
