"Lives on Fire" 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. Viewers witness the drama, action and danger of their jobs as they respond to life and death situations. 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 12 years of experience working in the service as a veteran firefighter/engineer; Rosanne Grier, who is in her fifth year as a seasonal firefighter working against the odds to become permanent; Michele Dyck, a veteran firefighter/engineer with 12 years of experience who works at a station in a coastal area known for its dangerous cliff and open water rescues; and Diley Greiser, a mother who is in her seventh year as a firefighter/paramedic who is adjusting to being the new person at Station 17 - one of the busiest and most demanding stations in Riverside County.
