Plot

Show takes us inside the extraordinary worlds of four remarkable women who risk their lives every day to take command during California's most dangerous disasters. As members of one of the nation's largest emergency response teams, these female firefighters are ready to battle against nature's most unforgiving forces. Witness the drama, action and danger of their jobs as they respond to life and death situations, all while facing the challenges of working in a man's world. With the ending of each shift, these women also open the doors into their personal lives as they strive to balance being mothers, wives, girlfriends and daughters. Viewers will follow four very different women including Nica Vasquez, a mother who has 15 years of experience working in the service as a fire apparatus engineer; Rosanne Grier, who is in her fifth year as a seasonal firefighter working to become permanent; Michele Dyck, a fire apparatus engineer with seven years of experience who adjusts to a transfer to a new station in Avila Beach, an area known for its dangerous cliff and open water rescues; and Diley Greiser, a mother who is in her seventh year as a firefighter and paramedic who delivers emergency medical care to patients on-scene at all kinds of incidents.—OWN
