Men dismissed, fixing finale (6)
I believe the answer is:
ending
'finale' is the definition.
(I've seen this before)
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for ending that I've seen before include "Climax" , "Gin den (anag.)" , "ultimately" , "Closure" , "Armageddon?" .)
