Have you ever heard a sound and not quite known what it is? It can be irritating and even unsettling. Now, imagine a lot of people in the same town begin to hear that sound? A hum – one that certainly merits further investigation. Enter self-professed slacker and Omagh-native, Phil Taggart, to get to the bottom of it all. A hard-nosed investigative journalist he is not, but there is no better man to examine the characters and quirks of the county Tyrone town where the strange sounds have been emanating. Across three episodes, Phil meets shopkeepers, scientist, comedians, councillors and musicians, all with a view to uncovering the source of the hum. In the final episode, Phil meets Jamie Ryan who claims to know the exact source of the hum. Will it prove to be an open and shut case or yet another dead end? Phil presses the Chair of Fermanagh and Omagh District Council on why they aren’t releasing more information about their findings in relation to the hum. He even tracks down the noise specialists the council engaged to locate the sound. Was it really driving some of the townsfolk to distraction? Finally, Phil comes to his own conclusions about this secretive, strange and surreal tale. So keep your ears peeled and your mind open as the investigation reaches its climax.
