This three part series investigates the San Francisco Fire Department based on information revealed from unnamed firefighters. In "Light Duty", hidden cameras show one officer works just 16 hours a week at his full time job, but still gets paid for 40 hours. Other light duty-or injured firefighters-get paid to watch for alarms, a job that could be eliminated and save tax dollars if the system was automated. Light duty officers are supposed to be restricted to one year of this recovery work, but this rule was not enforced. "Fire Raid" shows alcohol and drug use are problems at fire stations. One officer was found on duty with a blood alcohol level above the accepted limit and another tested positive for marijuana. A third officer drove a fire truck while taking medication that warns against operating hazardous machinery. In "EMS Mistake", the paramedic team is accused of not following protocol in response to an accident and causing the victim to be paralyzed. The investigation finds that other on-going investigations accuse paramedics of assault and even leaving a live woman for dead.
