The picture contains a story (4)
I believe the answer is:
epic
'a story' is the definition.
(I have seen 'Heroic story' mean 'epic' so perhaps 'story' could also mean 'epic')
'the picture contains' is the wordplay.
'contains' indicates a hidden word.
'EPIC' is hidden within 'the picture'.
(Other definitions for epic that I've seen before include "major work" , "On a grand scale like long poem" , "A long poem or book with adventurous theme" , "Heroic poem, film" , "Heroic narrative verse" .)
