The stage is set for the entrances (5)
I believe the answer is:
gates
'the entrances' is the definition.
(I've seen this before)
'the stage is set' is the wordplay.
'is set' is an anagram indicator (instruction to set the letters).
'stage' is an anagram of 'GATES'.
'for' acts as a link.
(Other definitions for gates that I've seen before include "Movable barriers in fence or wall" , "Confines (student) to college; entrances" , "Stage is set for them to open and close" , "One of the founders of Microsoft" , "Hinged barriers serving as entrances" .)
