This episode is a really high intensity one. At the conclusion of the last episode, Dubaku fights for his life. Jack has the paramedics remove a card from his chest. It contains information about all the embedded people in the government and the FBI. Chloe, who was brought in to help with the operation, is asked to decipher the card. Meanwhile, some serious efforts at sabotage are made. Things begin to cook. This is a great setup episode. We know, of course, with fourteen episodes still to go, there is not going to be an immediate solution.
