21 Bridges follows a disgraced NYPD detective (Boseman) who is given a shot at redemption. Thrust into a citywide manhunt for a cop killer, he begins to uncover a massive conspiracy that links his fellow cops to a criminal empire and must decide who he is hunting and who is actually hunting him. During the manhunt, Manhattan is completely locked down for the first time in its history — no exit or entry to the island including all 21 bridges.
