Episode 7

Police drama set in the 1980s.

What looks like a simple drugs-drop at a building site turns into a murder case when CID find a body buried in concrete. The site owner, Michael Lafferty, is working on major redevelopments to the London Docklands, and is resistant to having CID trampling on his turf. Many believe Lafferty is crooked - among them an eager young PC who thinks he's paying off his superior officers, plus several of the Polish workers he exploits.

All the while Alex is waiting, convinced she's recovering in the hospital and will wake up soon. However, the case begins to clash with her desire to get home and, when something occurs that shatters her view of how this world works, she is haunted by thoughts of her parents' death and whether she could have prevented it.

Desperate to get out of this increasingly confusing place, Alex is pushed to the limit. Just how far will she go to carve a path back home, and will she ever be able to share it with Gene?
