Hedging its bets , the manhunt movie “21 Bridges” both flatters and reviles the police. On the one hand, its somber hero, a remorseless homicide detective named Davis ( Chadwick Boseman ), is the closest thing the N.Y.P.D. has to a perp whisperer. On the other, Davis manages to shoot almost one suspect a month. Unapologetic about his kill rate, he explains to Internal Affairs that they all deserved their fates, so let’s move on, shall we?

Davis’s trigger finger — and a citywide police conspiracy — will be unduly tested when a cocaine heist goes awry and the thieves ( Stephan James and Taylor Kitsch ) escape by slaughtering eight police officers. Springing into action, Davis orders a complete blockade of Manhattan; with no way off the island, he and his blue army have just one night to catch the killers before the city implodes. Start the clock!
