What follows (6)
I believe the answer is:
sequel
'what follows' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for sequel that I've seen before include "Big film follow-up" , "Film continuing story of an earlier one" , "Novel or film that continues story of earlier one" , "Story resumption" , "A following episode wrapping up the plot" .)
