Bail out of special cage (5)
I believe the answer is:
scoop
'bail' is the definition.
(I've seen this before)
'special cage' is the wordplay.
'special' becomes 's' (common abbreviation as in Special Air Service).
'cage' becomes 'coop' ('coop' can be a synonym of 'cage').
's'+'coop'='SCOOP'
'out of' is the link.
(Other definitions for scoop that I've seen before include "Piece of news that no-one else has" , "Find utensil" , "Exclusive report" , "Large ladle" , "Exclusive story; utensil" .)
