Unruly lot entered plot and took flight (6)
I believe the answer is:
bolted
'took flight' is the definition.
(bolting is a kind of taking flight)
'unruly lot entered plot' is the wordplay.
'unruly' indicates an anagram.
'entered' is an insertion indicator.
'plot' becomes 'bed' (bed is a kind of plot).
'lot' with letters rearranged gives 'olt'.
'olt' inserted within 'bed' is 'BOLTED'.
'and' acts as a link.
(Other definitions for bolted that I've seen before include "Fled, having locked up?" , "Ran away" , "Fastened door with sliding bar (6)" , "Absconded" .)
