What’s the plot?

In series two, the story follows Grace, Annie and Tommy who are growing up fast as police officers, but nothing can prepare them for the turmoil they face every day.

It’s a year since the fall of the McIntyre crime gang and the vacuum has been filled by rival gangs, all competing for dominance. Constable Shane Bradley is drafted in to help, but his motivations are unclear.

Tommy is dangerously seduced by the world of intelligence policing, while Grace struggles to deal with her son’s absence, and growing feelings for fellow officer Stevie.

As a young loyalist threatens to take over the city, the officers face a major gangland feud – culminating in a violent and devastating confrontation.
