No job is more stressful, dangerous or exhilarating than those of the Firefighters, Rescue Squad and Paramedics of Chicago Firehouse 51.

They must survive on their own for a full 21 days, with nothing but one personal item each and the knowledge that the only prize is their pride and sense of accomplishment.
