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

'in?' is the definition.
Although both the answer and definition are singular nouns, I cannot see how one could define the other.

'play i promise a short run' is the wordplay.
'play' indicates an anagram.
'short run' becomes 'r' (cricket abbreviation; 'short' asks for an abbreviation).
'i'+'promise'+'a'+'r'='ipromisear'
'ipromisear' is an anagram of 'IMPRESARIO'.
