'where trouble flares up' is the definition.
The definition suggests a singular noun which matches the answer.

'son gets in a stew' is the wordplay.
I cannot really see how this works, but
'son' could be 's' (genealogical abbreviation for son) and 's' is found within the answer.
'stew' could be 'hotpot' (I've seen this before) and 'hotpot' is located in the remaining letters.
No letters remain.
This explanation may well be incorrect...

Can you help me to learn more?

(Other definitions for hotspot that I've seen before include "Nightclub" , "busy area" .)
