The premise

The host of a popular paranormal podcast becomes haunted by terrifying recordings mysteriously sent her way.

Horror Vault's take

A successful paranormal podcast host finds her professional curiosity curdling into personal terror when anonymous recordings begin arriving — and whatever is captured within them refuses to stay contained to the speakers. As the line between her work and her waking life dissolves, the hunt for the source becomes an increasingly dangerous descent. Undertone plays on the intimacy of audio and the creeping dread of something that can reach you anywhere you listen.
