Drama about an animal (3)
I believe the answer is:
ram
'an animal' is the definition.
(male sheep)
'drama about' is the wordplay.
'about' says the answer is hidden in the clue.
'RAM' is hidden in the letters of 'drama'.
(Other definitions for ram that I've seen before include "Temporary computer memory, initially" , "Zodiac sign; piston" , "'Computer memory, initially (3)'" , "Male sheep - bash into it" , "An animal; forcibly crash into" .)
