The Shield: Fire in the Hole

Aceveda learns of a mole in the Treasury Department leaking information about the Money Train heist, and the Strike Team must find the mole and plug the information leak to protect themselves. Upon locating the mole, they try, unsuccessfully, to get him out of Los Angeles for his own safety. The Strike Team and the Decoy Squad also find themselves muscling in on two negotiating gangs and are forced to work together, and when Trish and Claudette try to find a member of one of the gangs who is in on a child porn ring, they end up using him to help solve the cases for both police squads. Meanwhile, the problems with Matthew's autism at home worsen for Vic and Corinne.
