A film crew arrive in the area to shoot what looks like a spoof horror film. When Compo, Clegg and Foggy persistently interrupt rehearsals, the director has them recruited as extras, and they soon find a lot of people they know have also been recruited. Wesley has been hired to fix the generator, though he gets nowhere. For the luckless film director, Max Bernard, it is one disaster after another. Eventually, when the actor who is supposed to ride the horse passes out drunk, the director decides "if you want something done, do it yourself". But he gets more than he bargained for when the horse bolts after Barry's moped backfires.
