The new season of the NBC hit drama premieres Oct. 13 at 10 p.m.

Where in the world is Matt Casey (Jesse Spencer)?

That's the question of the hour when the new season of Chicago Fire kicks off Tuesday, Oct. 13 at 10 p.m. on NBC.

The first footage from season four of the hit drama picks up immediately after the events of the season three finale, with Dawson (Monica Raymund) finding a dead woman in Casey's ransacked apartment. Who does she call for help in her time of need? None other than Voight (Jason Beghe), who enlists the help of the rest of Chicago P.D.'s finest to bring Casey home.

Unfortunately, that's no easy task considering just who kidnapped one of Firehouse 51's most beloved employees. So who took Casey? And how will the rest of the firehouse handle his disappearance? Check out the season four trailer below.
