Unexpected endings (6)
I believe the answer is:
twists
'unexpected endings' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for twists that I've seen before include "Winds, turns around" , "Wrenches out of normal shape" , "Bends and turns out of shape" , "Distorts or misrepresent the meaning" , "plot changes" .)
