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

'prison camp caught out' is the definition.
I know nothing about this answer so I cannot tell whether this works.

'a feast of kiwis' is the wordplay.
I cannot quite see how this works, but
'a' could be 'an' and 'an' is located in the answer.
This may be the basis of the clue (or it may be nonsense).

'having' is the link.

Can you help me to learn more?
