What scares you? Not the fantasy stuff. Not the sparkly vampires or sexy werewolves. What wakes you up in the middle of the night in an icy sweat?

So much of what passes for ‘horror’ at the movies these days is painted in a thick coat of fantasy or over-the-top imagery. Whether it’s howling sculptures made from body parts or zombies snacking on the housekeeper’s femur, you can usually leave the theater or turn off the TV and comfort yourself with “That couldn’t really happen.”

But when you’re talking real horror, the one that strips away the comfortable jacket of fantasy, you get something like Right At Your Door, a quiet apocalyptic nightmare from writer/director Chris Gorak. It’s available on Netflix here, or you can watch it instantly here for $2.99 or buy it here for $12.99 on Amazon.

Modern day Los Angeles. Upwardly mobile couple Mary McCormack (In Plain Sight, Welcome to the Family) and Rory Cochrane (24, Argo, Parkland) live in a pretty nice house with a view overlooking downtown L.A. – we’re thinking Echo Park, but it’s debatable. They get up, she goes off to work in the city center, just like every day…but before she gets there three dirty bombs detonate during rush hour: at L.A.X., in Century City…and downtown, right near Mary McCormack’s office.

The first half of the film is about Rory’s character, Brad, coping with the rising panic, the contradictory radio reports, and sealing up the house against a massive cloud of toxic ash blowing uphill, straight towards their home. The second half shows what happens when Mary McCormack’s character, Lexi, makes it home.

There’s not an ounce of fantasy or sci fi in this piece; it’s just a way-too-up-close and personal story of what happens to two people in the 48 hours after the unthinkable happens, beautifully acted and directed (if you can call anything about this concept ‘beautiful’). It’s real horror here; it’s what really scares you. And it’s amazing it was Gorak’s first film. Not that he was brand new at this stuff when he made it in ’06; he spent the preceding 10 years as production designer or art director on a huge number of incredible movies, from Minority Report to Fear & Loathing in Las Vegas to Blade:Trinity to Fight Club. He directed a second film, The Darkest Hour, about alien invasion in Russia, a couple of years ago, and he’s just sold a new script that he’ll direct to the guys who produced Chronicle.

But this is the one that’ll get you. And it’s hiding someplace on your computer right now. If you really want to now what scares you; if you really want to movie to wake you up in the middle of the night…it’s Right at Your Door.
