The first trailer for Showtime’s upcoming police drama City On A Hill was just released. Based on an original idea from executive producer Ben Affleck and creator Chuck MacLean, the new series is set in early 1990s Boston, where corruption and racism was the norm in local law enforcement. The show features Kevin Bacon, who has appeared in Boston-set projects before in films like Mystic River, Black Mass, and Patriots Day, and now returns to Beantown for this gritty new crime drama.
