When a horror-loving radio show becomes the stage of a gruesome murder, its host Tinsel Monroe is put next on the killer's list… —- Tinsel Munroe's dream of working in radio hasn’t turned out to be everything she hoped it would. Sure, she has her own show – the aptly titled The Graveyard Shift – where she celebrates the sounds of horror-cinema. It’s a pop cultural oasis for the niche audience she has cultivated, but the wage is barely enough to cover her rent and the midnight hours are putting a strain on her relationship with tattooist boyfriend, Zack. After three years at Melbourne’s coolest station, she’s seemingly no closer to a prime-time slot. That is, until someone is murdered live on air. Mistaking it for a Halloween prank at first, a visit from police informs Tinsel that the hysterical call was, in fact, the real deal. She is freaked out by the horrible incident, but her true-crime obsessed sister Pandora is fascinated by it. While detectives assure them the killer will soon be caught, the bodies continue to drop with the killer striking at locations tied to Australian film history in increasingly gruesome ways. With a growing, macabre audience to her radio show, that potentially includes the killer, Tinsel begins receiving strange messages over the text lines. Her home and her workplace suddenly aren’t the sanctuaries she once thought they were. Tinsel and her sister are left no choice but to team up with Detective James as they race to find the connection between her and the culprit. The people she thought she could trust are now those she should fear the most. In order to survive, Tinsel is going to have to listen to more than just the airwaves…
