'all tantrums at close of play' is the definition.
I know nothing about this answer so I cannot judge whether this works.

'the tantrum to end' is the wordplay.
'the tantrum' becomes 'scene' ('scene' can be a synonym of 'tantrum').
'to' means one lot of letters go next to another (I've seen this in other clues).
'end' becomes 'last' (I've seen this before).
'scene' after 'last' is 'LAST SCENE'.
