Plug in marquee's animated front (10)
I believe the answer is:
masquerade
'front' is the definition.
(thesaurus)
'plug in marquee's animated' is the wordplay.
'plug' becomes 'ad' (as in plugging a product).
'in' means one lot of letters goes inside another.
'animated' indicates anagramming the letters.
'marquees' is an anagram of 'masquere'.
'ad' going within 'masquere' is 'MASQUERADE'.
(Other definitions for masquerade that I've seen before include "The wearing of disguise" , "Deception" , "Adam's queer? (anag)" , "Dress up" , "pose" .)
