Catches movie about conclusion of sit-down strikes (7)
I believe the answer is:
entraps
'catches movie' is the definition.
'entraps' can be an answer for 'catches' (entrapping is a kind of catching). I am not certain of the 'movie' bit.
'conclusion of sit-down strikes' is the wordplay.
'conclusion of sit-down' becomes 'ent' (I can't explain this - if you can you should give a lot more credence to this answer).
'strikes' becomes 'raps' (rapping is a kind of striking).
'ent'+'raps'='ENTRAPS'
'about' acts as a link.
Can you help me to learn more?
(Other definitions for entraps that I've seen before include "frames" , "nets" , "Catches" , "Takes" .)
