Toes the line (5)
I believe the answer is:
obeys
'toes the line' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for obeys that I've seen before include "Does what one is told" , "Complies with orders" , "Follows orders" , "Does as one's told" , "Submits to authority" .)
