Political journalist, Harry Constance receives some information from an ex fellow Oxford scholar, now UK MP, Martin King. The information could be enough to bring down the UK government if true.

As more is uncovered, they realise the precarious position they are in and the ease that they could be dealt with. Dead ends, false trails and threats lay in their path. All they have is their own expertise and dogged determination. The clock is ticking. Even if they find out what is about to happen, have they got time to stop it?
