A substitute teacher who’s young enough to vividly remember the horrors of adolescence finds another reason to fear high school when she realizes there’s something very strange about her new gig. The teachers are secretive and weird—and the kids are oddly obsessed with “the curriculum.”

Dan Samiljan’s horror comedy short The Sub is worth watching just for Zoe Jarman’s endearingly goofy lead performance. But that’s not all: The Sub also features a scream-tastic cameo by A Nightmare on Elm Street’s Heather Langenkamp, as well as some wonderfully retro stop-motion effects.
