City on a Hill (TV series)

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" and centers on an African-American District Attorney who comes in from Brooklyn advocating change and the unlikely alliance he forms with a corrupt yet venerated FBI veteran who is 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 city-wide criminal justice system. - IMDb
