Ian promised Kate that life with him would never be boring, but spending her days picking out paint colors and going to Pilates isn't going to cut it. Meanwhile, Ian discovers that building a white-hat security firm from the ground up seems harder the second time around, and he might have underestimated how much he'd miss the undercover work he walked away from. To make matters worse, the hacktivists are threatening national security, and the task force could really use Ian's help. Kate and Ian have always worried that their past would catch up to them, and when faced with the biggest showdown of their lives, they must capitalize on the one thing they excel at most: teamwork.
