Shirley Steadman, a 70 year old living in a small town in the North East of England, loves her volunteer work at the local hospital radio. She likes giving back to the community, and even more so, she likes getting out of the house. Haunted by the presence of her son, a reluctant Royal Navy officer who was lost at sea, and still in the shadow of her long dead abusive husband, she doesn’t like being alone much.

One day, at the radio station, she is playing around with the equipment and finds a frequency that was never there before. It is a pirate radio station, and as she listens as the presenter starts reading the news. But there is one problem - the news being reported is tomorrows. Shirley first thinks it is a mere misunderstanding - a wrong date. But she watches as everything reported comes true. At first, Shirley is in awe of the station, and happily tunes in to hear the news.

But then the presenter starts reporting murders - murders that happen just the way they were reported.

And Shirley is the only one who can stop them.
