Caught drum during finale (8)
I believe the answer is:
ensnared
'caught' is the definition.
(ensnaring is a kind of catching)
'drum during finale' is the wordplay.
'drum' becomes 'snare' (snare drum is a kind of drum).
'during' means one lot of letters goes inside another.
'finale' becomes 'end' (the end of a story or show).
'snare' put inside 'end' is 'ENSNARED'.
(Other definitions for ensnared that I've seen before include "Trapped" , "Caught in a trap" .)
