Are coins unearthed from plot? (8)
I believe the answer is:
scenario
'plot?' is the definition.
(I've seen this before)
'are coins unearthed' is the wordplay.
'unearthed' indicates anagramming the letters (anagrams must be unearthed or discovered).
'are'+'coins'='arecoins'
'arecoins' is an anagram of 'SCENARIO'.
'from' acts as a link.
(Other definitions for scenario that I've seen before include "Imagined situation" , "expected sequence of events" , "In plot of movie, for instance" , "Dramatic set-up" , "Outlines of drama" .)
