Faith represents Steve Baldini, a reformed criminal who may know something about her husband's disappearance. Back at the office, Tom makes a troubling discovery in the company archives that he believes will upset Faith's trust of her husband. DI Susan Williams, a vindictive police officer who has crossed swords with Faith in the past, turns her attention towards Faith's recent behaviour.

Fearing for her family's safety, Faith takes shelter in a hotel and meets with Steve, who tells her that Evan might have had links with a notorious family of drug dealers. As Faith looks into the lead, she is drawn deeper into Abercorran's sinister underbelly. Meanwhile, Bethan begins to feel the aftershocks of Marion's revelation. Dr Alpay proposes a deal to Cerys, and a disturbing discovery in the woods by Terry results in Williams building a case against Faith.
