Charlotte Bold is nothing like her name - she is shy and timid and just wants a quiet life. When her job doing the traffic news on the radio in London is relocated to Sunshine FM in Mumbles, she jumps at the chance for a new start in Wales.
But when she arrives she discovers that she's not there to do the travel news - she's there to front the graveyard evening show. And she's not sure she can do it.
Thrust into the limelight, she must find her voice and find a way to cope. And soon she realises that she's not the only person who finds life hard - out there her listeners are lonely, too. And her show is the one keeping them going.
Can Charlotte seize the day and make the most of her new home? And will she be able to breathe new life into the tiny radio station, too?
