Tinsel Munroe has busted her guts to get where she is. Yet her dream of working in radio hasn’t turned out to be everything she hoped it would. Sure, she has her own show – aptly titled – where she celebrates the sounds of cult-cinema, but the wage is barely enough to cover her rent and the midnight hours are putting a strain on her relationship with her boyfriend. Even 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, a visit from police informs Tinsel that the hysterical call was – in fact – the real deal. She’s freaked out, but her true-crime obsessed sister Pandora is fascinated. While detectives assure them the killer will soon be caught, the bodies continue to drop with the killer striking 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-in lines. Her workplace, and even her home, are suddenly not the sanctuaries she once thought. Tinsel and her sister are left with 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…
