Silent War: Episode 4

As Wyatt is tortured by Vartak's henchmen, Mac presses her corrupt lawyer to hand over an encrypted hard drive that might hold clues to the whereabouts of a pair of "nuclear suitcases." After being sorely tested in a deadly hostage standoff at an office building, the team is forced to lean on Zarkova to commandeer high-end Russian technology, crack the encryption code and make a final foray to a secret hideout, where Vartak, Gopan and the nuclear packages await.
