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

'makes premarital introduction briefly on arrival here' is the definition.
The definition suggests a singular noun which matches the answer.

'from overseas' is the wordplay.
I cannot quite see how this works, but
'from' could be 'in' (I've seen this in other clues) and 'in' is present in the answer.
This explanation may well be incorrect...
