When Tig finally discovers who is murdering the rapists, she must decide if she can turn a blind eye to a private quest for justice.

When Simon Prendergast is found dead, just as a positive DNA result confirms his guilt, it looks like another murder. Could the rapists be killing each other?

An arrest is made. But to defeat Simon's power games, and ensure they have enough evidence to charge him, Tig and Remi must walk a delicate tightrope.

Tig and her team, working almost around the clock, use digital traces and human detection to narrow in and finally identify the mysterious 'Jack'.

Although Tig and Remi are now dealing with a potential murder as well as a sexual assault, Quinn makes it clear they're going to have to spread already stretched resources across both cases.
