Film stars maybe caught escaping - they will be charged (4)
I believe the answer is:
ions
'film stars' is the definition.
The answer and definition can be both natural objects as well as being plural nouns.
Perhaps they are linked in a way I don't understand?
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for ions that I've seen before include "items with a charge" , "Electrically-charged particles" , "Charged atom or molecule" , "Electrically charged particles" , "N in radio comms." .)
