The Trick or Treaters (2016) online

During a mellow pre-Halloween night of drinks, pranks and old horror films, Amy and Jake film a last minute schedule video for their school's annual Halloween fundraiser, but they are quickly interrupted by a strange group of trick or treaters, also equipped with a video camera. Dismissing it as a prank by their friends, they ignore the strange interruption and continue with their night. As strange things continue to occur and escalate to an extreme level, the students quickly discover that they are dealing with dark individuals...and they don't want candy.
