21 Bridges

In the trailer for 21 Bridges, An NYPD detective who obsesses over cop killers due to the death of his police officer father as a child, is brought in on an armed robbery case that resulted in the deaths of eight cops. Deducing that there were two gunmen, he orders the closure of all 21 bridges, four tunnels, and three rivers leading out of Manhattan to track down the killers. But as he nears his two targets, the detective soon finds that there is more to this case than meets the eye.
