Fire Country revolves around a group of prisoners assisting the California Department of Forestry and Fire Protection, aka Cal Fire, via the California Conservation Camp Program. Cal Fire is a real-life fire department on the West Coast that protects millions of acres of forests. However, members of Cal Fire have publicly denounced the CBS drama series' interpretation of their program, making it known that the show is not an authentic depiction of how the group operates in California.
