Wretched play entertains British setter in Caen (6)

I believe the answer is:
abject
'wretched' is the definition.
(I've seen this in another clue)
'play entertains british setter in caen' is the wordplay.
'play' becomes 'act' (synonyms).
'entertains' means one lot of letters goes inside another.
'british' becomes 'b' (abbreviation e.g. in 'BBC').
'setter in caen' becomes 'je' (I am not sure about this - if you are sure you should believe this answer much more).
'b'+'je'='bje'
'act' going around 'bje' is 'ABJECT'.
Can you help me to learn more?
(Other definitions for abject that I've seen before include "Mean, wretched" , "Down-hearted" , "This apology shows humility" , "Completely without pride" , "Extremely humble" .)
