Trick or Treaters in the post-apocalypse or is it just San Francisco?

Four kids in traditional costumes go out for candy and find a survivalist house with loads of guns, but hey candy is on the line! The home is occupied buy a very tired husband and wife.  The wife is getting sick, but it appears that the kids might be in the house!!!

The wife disappears and the husband is confronted by one of the kids in a ghost costume. These aren’t ordinary trick or treaters and those costumes aren’t store bought!!!!  It’s kind of cool figuring out what’s going on in the end.  It’s a very fun short!
