Dave Franco and Alison Brie are dealing with something much darker than just relationship drama in the newly released trailer for Together.

The footage, set to a peaceful piano melody, depicts something quite less tranquil than its respective music as the bodyhorrorromance sees the couple being put to the test by a mysterious, unnatural force, leading to the ultimate nightmare.

I love you, a weathered Franco says at the end of the trailer released Wednesday, to which a tearful Brie responds, I love you too. Years into their relationship, Tim (Franco) and Millie (Brie) find themselves at a crossroadsas they move to the country. Abandoning, all that is familiar in their lives except each other. With tensions already flaring, a nightmarish encounter with a mysterious, unnatural force threatens to corrupt their lives, their love and their flesh, the films official logline reads.

The movie was written and directed by Michael Shanks, with Brie, Franco, Mike Cowap, Andrew Mittman, Erik Feig, Julia Hammer, Tim Headington and Max Silva serving as producers. Damon Herriman also stars.

Following its premiere at Sundance earlier this year, David Rooney, The Hollywood Reporters chief film critic, wrote in his review, Shanks could stand to develop more finesse (and better writing) in the emotional drama. But even if hes killing time in his first feature before letting loose a heap of corporeal mayhem,Togethermarks him as a talent to watch. Its an ideal midnight date movie for the non-squeamish.

Neons Together hits theaters on Aug. 1.
