I believe the answer is:
sequel
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">follow-on story</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this before)</span><br/ ><br/ >This is the entire clue.<br/ ></span>
(Other definitions for sequel that I've seen before include "Continuation of an earlier story" , "Novel or film that continues story of earlier one" , "Programme or work following on from another" , "Following film" , "Story resumption" .)
