Sheriff Jamey Noel has devised an unprecedented program to root out crime and corruption in the Clark County Jail.

As they close in on the one week mark, the survivalists make some risky choices in order to eat. Serious infection becomes a very real possibility.

The remaining survivalists start seeing their hard work pay off as they procure food.

The survivalists get serious about hunting before the wildlife starts to disappear for the winter. One participant finally has a chance to make Alone history by taking down big game, while another is set back by a nasty puncture wound.

While most of the participants pursue smaller, more consistent food sources, one survivalist finally has the chance to take down big game.

As they approach the one month mark, the participants' survival is threatened by new factors. One contestant is forced to defend themselves from a huge predator.

As winter closes in, the participants are threatened by predators looking to steal their precious food stores. As the survivalists rethink their strategies, one makes a stand.

The remaining survivalists begin feeling the effects of starvation. One participant fights to stay in the competition as her body starts to give out.

As the weather gets colder and even less forgiving, the participants struggle to obtain basic resources. One participant continues to lose weight at a rapid and deadly pace.

As temperatures drop to the lowest point yet, the lake freezes, cutting off resources and threatening the safety of the survivalists.

The final three survivalists continue to battle weight loss, extreme temperatures, and predators to remain in the fight for the $500,000 prize.

As pressure builds in each of the jail's pods, the five remaining participants in the program try to finish up their final few days inside.

Three participants remain in Clark County Jail. One of the women in F-Pod is released, leaving Tami on the verge of a meltdown.

All seven participants meet for the first time to discuss their experience inside. Tempers flare when the women relive a contentious moment while in the jail.

After serving time in the dangerous world of the Clark County Jail, Barbra, Robert and Tami are released, look back, and share never-before-seen insight into their time in jail.

After serving time in the dangerous world of the Clark County Jail, Zac, Isaiah, Jeff and Maryum are released, look back, and share never-before-seen insight into their time in jail.
