It tells the story of Georgia Nolan, a 16-year-old girl who dreamed of becoming a firefighter when women were not allowed to do so. When a mysterious arsonist began to burn down Broadway, all the firefighters in the city disappeared one by one, and Georgia's retired father, Sean, was recalled by the mayor of New York to lead the fire department investigation. To help her father and save her city, Georgia disguised herself as a young man named Joe, joined a team of out-of-place firefighters and tried to stop the arsonist at all costs.
