I believe the answer is:

epic

I'm a little stuck... Click here to teach me more about this clue!

'a long narrative' is the definition.
(I've seen this in another clue)

'the picture encapsulates' is the wordplay.
'EPIC' is hidden within the letters.
However, I'm uncertain how the hidden word is indicated.

Can you help me to learn more?

(Other definitions for epic that I've seen before include "Exodus, say" , "Ben Hur, say" , "Long poem - awesome!" , "long poem telling of heroic deeds" , "Tale of heroic deeds" .)
