DCI John Luther follows the rules of law but he also allows his gut to be his guide. He's paid a heavy price for his obsessive dedication – his wife Zoe was brutally murdered by Luther's old colleague and former best friend Ian reed. Luther is struggling to accept the loss of his wife and escape the reputation that he's tainted and brings chaos to all he touches.
With the establishment of the new Serious and Serial Crime Unit, Luther is given the opportunity to make amends and redeem Justin Ripley's career. But in order to do so, he once again throws himself into his work and becomes immersed into the dark and dreary world of crime.
