Written by Chuck MacLean (Boston Strangler) based on an original idea by Affleck and MacLean, City on a Hill is set in Boston in the early ’90s when the city was rife with violent criminals emboldened by local law-enforcement agencies, in which corruption and racism was the norm, until it all suddenly changed. The drama is a fictional account of what was called the “Boston Miracle.” The change agent is District Attorney Decourcy Ward (Aldis Hodge), who comes from Brooklyn and forms an unlikely alliance with Jackie Rhodes (Kevin Bacon), a corrupt yet venerated FBI veteran who is deeply invested in maintaining the status quo. Together they take on a family of armored car robbers from Charlestown in a case that grows to encompass and eventually upend Boston’s citywide criminal justice system.
