As the season begins, the fallout from Russia's thwarted attack on London finds the team in a race against time to rescue Harry, who has been kidnapped by rogue Russian agents. But as they dig deeper into his disappearance, they find a trail that leads to Iraq, and a conspiracy that involves the CIA, MI-6 and some missing weapons-grade uranium. Special features included.
