PONTYPOOL at Wales Millennium Centre

Don’t. Breathe. A word.

Radio DJ Grant Mazzy was once king of the airwaves, but his big mouth and even bigger ego have reduced him to a washed-up star. Forced to leave the national stations behind, he finds himself at Beacon Radio, Pontypool’s little-known station in the South Wales valleys.

On a snowy St Dwynwen’s Day, Mazzy and his team settle in for another breakfast show of news, weather, traffic and call-ins. But things take a disturbing turn when muddled reports come in of an outbreak of riots and babbling crowds in the town.

Panic spreads. Terror closes in. Can Mazzy remain on air to make sense of it all, or will Pontypool fall silent?
