The National Security Agency knows who Martin really is. They offer to clean his record, but he has to steal a "black box" from a mathematician, Dr. Gunter Janek. Janek made the box for the Russian government. Martin agrees to help. With help from his former girlfriend, Liz, Martin and his team get the box, which is disguised as an answering machine. Whistler, Mother, and Carl discover that the box can break the encryption code of nearly every computer system. Martin says no one can leave the building until they can deliver the box the next day.
