Scene one disturbed relatives (6)
I believe the answer is:
nieces
'relatives' is the definition.
(niece is a kind of relative)
'scene one disturbed' is the wordplay.
'one' becomes 'i' (Roman numeral).
'disturbed' is an anagram indicator (the order of letters is disturbed).
'scene'+'i'='scenei'
'scenei' anagrammed gives 'NIECES'.
(Other definitions for nieces that I've seen before include "Relatives of 27dn" , "They're family" , "Relative girls" , "Relations" , "Young female relatives" .)
