Contorts (6)
I believe the answer is:
twists
'contorts' 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 "Interweaves or gives spiral form to" , "Wrenches out of normal shape" , "Winds, turns around" , "Rotates rapidly" , "plot changes" .)
