'something dramatic' is the definition.
I can't judge whether this defines the answer.

'in a score possibly' is the wordplay.
'possibly' indicates an anagram.
'in'+'a'+'score'='inascore'
'inascore' with letters rearranged gives 'SCENARIO'.

Can you help me to learn more?

(Other definitions for scenario that I've seen before include "Projected sequence" , "Film/novel plot outline" , "Outline of film, novel, etc" , "Postulated sequence of events" , "Summary of plot of play" .)

I've seen this clue in the Evening Standard.
