Season three of CITY ON A HILL brings us to Boston's high society Beacon Hill. Having left the FBI and thrown his badge into Boston Harbor, Jackie Rohr (Bacon) lands a lavish new gig running security for a wealthy family. Life is good until secrets begin to unravel. When an investigation opens, ADA Decourcy Ward (Hodge) sees an opportunity to finally rip out the machinery perpetuating a broken criminal justice system. Siobhan Quays (Banks), representing a construction worker who was severely injured on the Big Dig, encounters the city's corruption firsthand, all while coping with the traumatic events of her past year. As Jenny Rohr (Hennessy) can attest, given her history with her father, some experiences will haunt you beyond your breaking point.
