Following the arson fire that led to the collapse of a warehouse, the firefighters of 62 Truck are recovering from their physical and emotional wounds – all, that is, but Lou Shea, who died leading his men to safety. As a result of his best friend’s tragic death, Tommy has been made acting lieutenant of 62 Truck, giving him all the responsibility he has avoided during his long career. Along with leading the firehouse until a new lieutenant is appointed, Tommy is planning Lou’s memorial service, even as he remains haunted by the memories of his death. So, as Tommy tells Janet that he has decided to retire, his friends at work also look ahead to their own futures inside and outside the department. Though determined to honor his promise to retire, all it takes is one afternoon at the park with Katy and Wyatt for Tommy to wonder if he can cope with the lifestyle change. Following an unfortunate accident en route to the seaside service that prematurely scatters most of Lou’s ashes across the highway, Mickey leads the late firefighter’s friends in a comic and moving tribute. And when Tommy reads a letter Lou left to be opened upon his death, the men of 62 Truck are reminded that they are a team that deserves to stay together even after he’s gone. Back at home following the memorial, the Gavin family is preparing to relax over a pizza when Janet goes into labor. With her labor too far advanced to make it to the hospital in time, Tommy leads his family in the successful delivery of a baby boy, and then faints dead away on the floor. Knowing that there’s no way he could ever stay at home, Janet suggests Tommy take a job as a drill instructor at the fire department training academy. But after just a few days of driving Janet crazy with his complaining, Tommy returns to duty at 62 Truck alongside his friends and their new boss, Lieutenant Franco Rivera. © 2011 Sony Pictures Television Inc.
