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

'note above plate' is the definition.
The definition suggests a singular noun which matches the answer.

'fish caught by eccentric character' is the wordplay.
'fish' becomes 'plaice' (plaice is a kind of fish).
'caught' shows a homophone (sound like) (heard).
'by eccentric character' becomes 'card' (I can't explain this - if you can you should believe this answer much more).
'plaice' sounds like 'place'.
'place'+'card'='PLACE CARD'
