Turn the volume up, and maybe leave the lights on. The first trailer for undertone has dropped, and it is already vibrating at a frequency that horror lovers would want to tune into immediately.

From writer-director Ian Tuason comes this A24 release that promises a new sound in horror—that gets right under your skin and stays long after the last note has ended.

Nina Kiri, Adam DiMarco, Michèle Duquet, Keana Lyn Bastidas, and Jeff Yung star in undertone and it looks like they won’t be meddling with cheap jump scares but something way more unsettling: atmospherics, dread, or the kind of tension you can practically hear. The trailer teases an experience that’s moody and mysterious. It carries that scent which is unmistakably A24 - stylish, strange, and sharp with emotions.

See the first trailer below, look at the haunting poster, and get your senses ready.

U\undertone will be in theaters for just one night on Friday, March 13 only from A24. Hear that? Something’s coming.

Here's a look at the first trailer for undertone:
