Without restrictions, her brood lands abroad (2,5,6)
I believe the answer is:
no holds barred
'without restrictions' is the definition.
(I've seen this before)
'her brood lands abroad' is the wordplay.
'abroad' is an anagram indicator.
'her'+'brood'+'lands'='herbroodlands'
'herbroodlands' anagrammed gives 'NO-HOLDS-BARRED'.
(Other definitions for no holds barred that I've seen before include "Without regard for fair play" , "Anything goes" , ""All's fair"" , "Not observing the rules of fair play" , "there are no limitations" .)
