Hides and shows (7)
I believe the answer is:
screens
I believe this is a double definition.
'hides' is the first definition.
(I've seen this in another clue)
'shows' is the second definition.
(screen can mean to show a film)
'and' acts as a link.
(Other definitions for screens that I've seen before include "Covers to conceal" , "Shows on the telly" , "vets" , "Checks" , "for security guards" .)
