Abigail Corbin is a chatterbox podcast host who believes that The Signal might have a supernatural source. To help her investigate, she tracks down renowned paranormal investigator James Hunter, now living as a reclusive alcoholic. The two form an unlikely partnership as they investigate all things unexplained, spooky and potentially life-threatening. Doctor Who meets The X-Files in this serialised audio drama which features memorable characters, plenty of fear, moments of comedy and a interweaving narrative that unfolds over the course of the show.
