STX Entertainment has unveiled the first trailer for “21 Bridges”.

The jam-packed new teaser features “Black Panther” favourite Chadwick Boseman as “a disgraced detective who gets a shot at redemption as he pursues a cop killer through the streets of New York City.”

Boseman’s character goes to the extreme to catch the killers: closing down tunnels, sealing off rivers, and shutting down 21 bridges.
