James Purefoy stars as William Travers a criminal barrister who is recovering from a traumatic series of events that have shaken his belief in the legal system.
On the surface Travers is a picture of success; an accomplished criminal barrister happily living with his wife (played by Dervla Kirwan) in rural Suffolk.
However Travers is still recovering from events in his past when he is drawn into a case that involves his old friend Martin Newall (Nathaniel Parker) who faces conspiracy and murder charges while at the same time being investigated by a vicious and vengeful detective DS Mark Wenborn (Creed Miles).
The five-part series from acclaimed writer Anthony Horowitz (Collision Foyle's War) is a story of friendship conspiracy betrayal and murder as well as a critical look at the way the legal system operates.
