The veil between hell and our world is as thin as a scream.

Narisa grieves for her husband with a pain so great, she wants nothing but to join him in death. But on the verge of taking her own life, he contacts her through one of their antique 1930s radios and pleads with Narisa through screams for her to rescue him from hell. Being a highly intelligent Sound and Communications Engineer, she’s the only one who can do it. Narisa gets to work on searching for the exact resonance frequency that will pierce the veil and save her husband. But the first attempt ends in disastrous results.

Demon spirits push through and possess her apartment building.

Now frantic, Narisa deals with being trapped in the building with other tenants as gruesome and fantastic murders begin. She still wants to save her husband, but now she struggles with reversing her mistake before more people die. After gathering and assembling the equipment she needs to try again, she turns it on and dials the right frequency. Not until then does she understand that she’s been used.

A demon, not her husband comes through the veil.
