　　The central character is Detective Chief Inspector Vera Stanhope. Who is obsessive about her work and driven by her own demons. If she's lonely she doesn't show it and faces the world with caustic wit, guile and courage. Her trusted and long suffering colleague is Sergeant Joe Ashworth. Together they approach every new case with unparalleled gusto and professionalism.

　　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.
