Depict entertaining story (4)
I believe the answer is:
epic
'story' is the definition.
(I have seen 'Heroic story' mean 'epic' so perhaps 'story' could also mean 'epic')
'depict entertaining' is the wordplay.
'entertaining' indicates a hidden word.
'EPIC' is hidden within 'depict'.
(Other definitions for epic that I've seen before include "Of heroic proportions" , "Long account" , "Large in scale" , "Long adventure story" , "long poem telling of heroic deeds" .)
