Air film with that woman (5)
I believe the answer is:
ether
'air' is the definition.
(literary term for the air or sky)
'film with that woman' is the wordplay.
'film' becomes 'et'.
'with' is a charade indicator (letters next to each other).
'that woman' becomes 'her' (I've seen this before).
'et'+'her'='ETHER'
(Other definitions for ether that I've seen before include "It could knock you out" , "Type of chemical" , "Volatile solvent" , "Solvent; clear sky (poet.)" , "Liquid used as anaesthetic/ solvent" .)
