Drama about sheep (3)
I believe the answer is:
ram
'sheep' is the definition.
(male sheep)
'drama about' is the wordplay.
'about' says the answer is hidden in the clue (the clue goes around or about the answer).
'RAM' can be found hidden inside 'drama'.
(Other definitions for ram that I've seen before include "Computers need it to operate" , "Computer memory of a sheep?" , "Butter" , "'Computer memory, initially (3)'" , "Aggressive sheep?" .)
