After her husband is killed while working under cover, Jo begins to question everything she thinks she knew about her husband and his work.

With the arrest of Michael Parry, the last member of the gang that Ryan had infiltrated, the rest of the police force seems to accept that the investigation into his murder is over. But to Jo, the truth seems further away than ever.

Suspended from duty, Jo turns her back on Ryan’s investigation and focus on looking after her family. However, the discovery of a body throws Jo back into the unavoidable course of danger.
