City on a Hill

In early ‘90s Boston, racism is endemic and crime is widespread. Jackie Rohr, a renowned FBI agent whose methods are not exactly by the book, does not mind the status quo. But Decourcy Ward, the new Assistant District Attorney in town, wants to uproot the corrupt system. The two form an unlikely, and obligatory, alliance to take down a gang of armored truck robbers from Charlestown.

After an eventful Sunday at church, Decourcy finds out he has a new powerful enemy in town — one that puts his wife Siobhan in an awkward position. Jackie is stirring up trouble in his own home, and his distrustful mother-in-law Rosa is onto him. Investigators Hank Signa and Rachel Behnam look into an unsolved missing persons case connected to the robbery in Revere. That could mean trouble for Frankie Ryan, who's busy laundering his most recent loot and, with the help of his brother Jimmy, getting carried away in the process.

Jackie searches for his absent informant as Jenny searches for purpose, revisiting her passion to become a teacher. Decourcy works up a plan to overcome the town's infamous "Code of Silence" and get a few suspects to talk. Minogue is assigned a big case, but not the one he actually cares about. Jimmy skips town to visit his kids and finds that, even a thousand miles away, he's not safe from his problems back home.

When an assistant U.S. attorney overdoses and ends up left for dead, Decourcy Ward suspects Jackie Rohr's involvement. Jackie, in turn, goes after the BPD for a questionable drug arrest at Braxton Summit, a federal housing project. Community activist Grace Campbell recruits Siobhan Quays to work on behalf of Braxton and its residents, but their efforts are subverted as tensions flare between rival gangs.

As Decourcy increases pressure on the Justice Department, Jackie counters by looking into his adversary's romantic past. While Jackie's digging up dirt, Siobhan is planning ahead, focused on starting a family even as Decourcy remains preoccupied by the escalating conflict. Jenny realizes she can't keep ignoring her mother after an unsettling phone call. With business at the salon all but dead, Cathy Ryan turns to an unlikely income source.

Jackie uncovers one of Decourcy's informants and hatches a plan to use him as a pawn to discredit the assistant district attorney. Decourcy stops by the Rohr house, hoping to get something out of Jenny that he can use against her husband. Siobhan receives some welcome news, in the midst of plotting her run for City Council. And her client, Kelvin Campbell, is released from custody, though he can't free himself of what happened on Valentine's Day. Jimmy Ryan, meanwhile, faces problems far worse than a guilty conscience.

Struggling to make ends meet after leaving the FBI, Jackie Rohr gets a job offer from his old mentor. The perks are enticing, but Jackie has no idea what he's getting himself into. ADA Decourcy Ward eyes a promotion but is diverted by some bad news which lands him back in Brooklyn. Siobhan Quays, having left her prestigious law firm for a position at the ACLU, takes on a case against a construction colossus. Jenny Rohr begins volunteering at a community center where she runs into a familiar face.

When Victoria Dryden runs away from home, Sinclair sends Jackie to find her. Caysen is after justice for BPD Officer Russ Wallace, who he believes may have been intentionally executed by another member of the Strike Force. The incident sparks a dispute at the Ward home in Brooklyn, where Decourcy is looking after his ailing father. While building a case on behalf of her impaled client, Siobhan experiences an intensifying array of symptoms. Diarmuid Doyle tries to help Jenny remedy what has been bothering her, but his plan backfires. 

Vying to become Boston's next DA, Decourcy takes on a murky case involving a murdered police officer. He recruits the help of Caysen, who is becoming increasingly alienated from the officers in his unit. As the Drydens try to solve their Victoria problem, the Rohrs drop Benedetta off for her freshman year at NYU. They return empty nesters but to no peace and quiet. When Siobhan receives a distressing phone call, a dark secret resurfaces.
