The guys are trying to nab a man named "Alex Deckard" here, a tough cookie, as they say, to get. They need the grab him to get to another, bigger man up the crime chain: an arms supplier for Iran. "Deckard" (Lee Tergesen), a former rogue agent with The Unit, got him arrested by some fluke, in Bulgaria. Word is he is ready for an escape out of the prison and the U.S. doesn't want to lose a chance at grabbing this man, so the team - with an inside man - is there to get him, and then make a proposal they hope he accepts to help nail the arms dealer.
The secondary story involves Molly Blane's efforts to recruit for another organization so that she can earn extra money to help put her mother in a good nursing home. That doesn't make Colonel Ryan too happy. It doesn't make her neighbor Kim happy, either, as Molly used her to get to a potential client. (Molly spent much of the first season of this show lying to people and almost always was given a pass for it, as she does here, too. It's ridiculous.)
Anyway, the jail escape scene was tense and the scene with the Russian at the small airport was shocking. The episode as a whole was very entertaining. as usual.
