City street incident. The play finishes with it (4,5)

I believe the answer is:

last scene

I'm a little stuck... Click here to teach me more about this clue!

'play finishes with it' is the definition.
I don't know anything about this answer so I can't tell whether this works.

'city street incident' is the wordplay.
'city' becomes 'LA' (Los Angeles).
'street' becomes 'st' (abbreviation).
'incident' becomes 'scene' (scene is a kind of incident).
'la'+'st'+'scene'='LAST SCENE'

'the' acts as a link.

Can you help me to learn more?

I've seen this clue in the Sydney Morning Herald.
