Tommy Gavin is a lifesaver. Whether he is pulling survivors from fiery high-rise infernos or the twisted steel of a subway collision, Gavin takes great pride in leading the heroic but often overwhelmed firefighters of New York City's Truck Company 62. Gavin is also a man drifting between sorrow and anger over a recent separation from his wife and three kids, and recurring memories of comrades and other New-Yorkers who fell victim to the tragedy of 9/11.
