She shows Poles around the States (5)
I believe the answer is:
susan
'she' is the definition.
'poles around the states' is the wordplay.
'poles' becomes 'sn' (North and South poles).
'around' is an insertion indicator.
'the states' becomes 'usa' (I've seen this before).
'sn' enclosing 'usa' is 'SUSAN'.
'shows' is the link.
(Other definitions for susan that I've seen before include "Girl's name, meaning lily" , "When lazy, she's a revolving tray on a dining table" , "sometimes lazy, passing round the condiments" , "She's a black-eyed flower" , "- - Sarandon, film actress" .)
