Luther

A chance encounter means Luther might be on the verge of finding love. However, nothing comes easily - not when a fetish killer is on the hunt, not when an internet tormentor has had the tables turned and not when his worst enemies are his own colleagues.

Luther's date with Mary, and the promise of romance, is interrupted by the news of another murder. The killer has struck again and the number of victims is escalating fast. Faced with the repercussions of their public disagreement, Luther orders Ripley to investigate the Jared Cass murder on his own. Meanwhile, he throws himself into a mountain of cold case files, determined to connect the past and present.

A vigilante killer begins a crusade to punish past offenders, forcing Luther to confront his demons. Meanwhile, the plot within the force to bring him down threatens everything he holds dear.

Accused of crimes he didn't commit, Luther rushes to clear his name and prevent the vigilante killer from becoming a martyr, but he risks the lives of those he loves when he becomes the killer's target.
