I need to make a halloween movie for work, anyone have a good idea for a scary short film?

The only requirements are: Has to be SFW obviously, and has to have something to do with halloween, or scariness. approx. 5 min, and I don’t really wanna do anything too cheesy. I’m pretty good at video editing, so I can make it look nice, the problem is we want to do a scary short movie, but we’re lacking on story ideas. We have a few scary locations picked out though. O, and I work at a video game company, so if that could be factored in somehow it would be cool, but not necessary.

Any help would be greatly appreciated!!
