Stagger to see a film (4)
I believe the answer is:
reel
This clue is a double definition.
'stagger' is the first definition.
(both can mean to move around without balance)
'film' is the second definition.
(I know that reel is a type of film)
'to see a' acts as a link.
(Other definitions for reel that I've seen before include "Lively dance; bobbin" , "long stretch of film" , "Photographer's and anglers spool" , "Revolving spool" , "Dance; winding drum" .)
