Two Ts (S04E16)

Casey (Jesse Spencer) continues his run for alderman, but a citywide propaganda attack against his campaign makes him reconsider his candidacy. The rescue squad is summoned to the scene of a man trapped inside of a burning car with suspicious evidence suggesting that the fire may have been intentionally set. Mouch's (Christian Stolte) upcoming bachelor party looms, but with Trudy's (Amy Morton) nerdy brother Larry (Zack Pearlman) handling the details, everyone fears for the worst. Meanwhile, Jimmy (Steven R. McQueen) and Brett (Kara Killmer) take a kidnapping investigation into their own hands. (iTunes)
