The first trailer for director Adam Wingard's horror film You're Next is now online.  The story centers on a family reunion that turns deadly when the family becomes targeted by masked murderers.  Their only hope is Erin (Sharni Vinson), a girlfriend of one of the family members. I really dug the flick when I saw it at TIFF 2011, and I'm excited that it's finally coming out.  The trailer feels a tad on the generic side, but it doesn't give away too much, and I like the use of Lou Reed's "Perfect Day".

Written by Simon Barrett, You're Next also stars Joe Swanberg, AJ Bowen, Amy Seimetz, Barbara Crampton, Wendy Glenn, Margaret Laney, Rob Moran, and Nicholas Tucci, and Ti West.  The film opens August 23rd.  Hit the jump to watch the trailer.

Here's the synopsis for You're Next:

One of the smartest and most terrifying films in years, YOU’RE NEXT reinvents the genre by putting a fresh twist on home-invasion horror. When a gang of masked, ax-wielding murderers descend upon the Davison family reunion, the hapless victims seem trapped…until an unlikely guest of the family proves to be the most talented killer of all.
