The courageous firefighters, rescue squad and paramedics of Chicago Firehouse 51 return for the explosive eighth season of Chicago Fire, the fiery drama from powerhouse executive producer Dick Wolf. With Captain Matthew Casey (Jesse Spencer) leading the truck company and Lt. Kelly Severide (Taylor Kinney) heading the rescue squad, the Firehouse 51 family faces dangerous new challenges this season as they continue to put their own lives on the line to keep others safe. When we last saw our heroes, they were racing to rescue workers trapped inside of a burning mattress factory. With an industrial boiler threatening to explode at any moment, can Chicago's bravest make it out safely before the blast takes out the whole block?
