Rescued broken contracts (7)
I believe the answer is:
reduces
'contracts' is the definition.
('reduce' can be a synonym of 'contract')
'rescued broken' is the wordplay.
'broken' is an anagram indicator.
'rescued' is an anagram of 'REDUCES'.
(Other definitions for reduces that I've seen before include "Secured (anag.)" , "Lowers" , "contracts" , "Takes off, weight say" , "Makes smaller or lower" .)
