The house of cards Harvey and Mike have built may finally come tumbling down when Mike is taken in for questioning by US Attorney Eric Woodall. It seems that Woodall has got wind of the Hessington settlement, and the tenacious attorney smells blood. But as Woodall soon makes clear, he doesn't really want Mike; it's Harvey he's after, and he's willing to make a deal with his protégé in order to get him.
Mike has no intention of turning on his mentor, but as he and Harvey scramble to cover their bases it becomes evident that they still have a major liability on their hands, and his name is Harold Gunderson. At the same time, news of Mike's brush with Woodall causes the employees of Pearson Hardman to take a hard look in the mirror, and they may not like what they see.
Meanwhile, when Mike and Harold are arrested, Mike hopes his timid ex-colleague will toe the line. But Woodall is a man who gets what he wants at any cost, and when Harold begins to crack under the pressure, even some help from an unexpected source may not be enough to save Mike from paying the ultimate price for his loyalty to Harvey.
