Action film sequence (5)
I believe the answer is:
chase
'action film sequence' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for chase that I've seen before include "grave, as before?" , "Engrave - hunt - pursue" , "Hurry" , "groove" , "Pursue; decorate (metal) by engraving" .)
