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. Robert gets a taste of Tami's wrath when confronted about not taking the program seriously.

Three participants remain in Clark County Jail. One of the women in F-Pod is released, leaving Tami on the verge of a meltdown. Meanwhile in D-Pod, with one pod boss removed and another claiming power, there is a constant threat of violence.

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.

As the participants near the end of their time in jail, tension in F-Pod pushes one woman over the edge and compromises the program, while both men in D-Pod struggle to avoid criminal activity that may have serious consequences

Thanksgiving presents new opportunities and challenges for the six remaining participants, and one of them is pushed to a breaking point.

The participants cross the halfway point of the experiment; the sheriff orders a raid due to increased tensions and drug activity in D-pod; the residents of F-pod worry about a contagious rash.

Inmate Ricky attacks Jeff, jeopardizing the program; Zac and Isaiah move from the familiar confines of C-Pod to the more violent D-Pod; Barbra feels betrayed by her F-Pod bunkmates; Robert learns that he will return to general population.

As the participants approach the midway point, tension and anger grow among the women in F-Pod, while one of the men finds himself in imminent danger from the inmates in C-Pod.

An unexpected call to court tests Zac's strength as an inmate; Barbra abandons a friendship with Tami in order to survive; a series of catastrophic mistakes endangers Jeff.

Isaiah and Robert worry that their covers may be blown; Capt. Maples follows through with consequences after Robert makes a risky move; Zac hunts for illegal drug use in C-pod; Tami clashes with another inmate.

Maryum, the eldest daughter of boxer Muhammad Ali, joins the program and fits into F-pod effortlessly; the inmates grow suspicious of Robert; a mistake places Zac in peril; Barbra questions her commitment to the experiment.

Sheriff Jamey Noel's program is underway. Zac, a Marine, Tami, a police officer, Robert, a teacher, and Barbra, a stay-at-home mom, are the first participants in. Will they make it through the first 24 hours inside?

Sheriff Jamey Noel has devised an unprecedented program to root out crime and corruption in the Clark County Jail. His plan is to send seven civilian volunteers into jail as undercover inmates. The participants all have unique motivations for joining the program, and have been given cover stories, training on the rules of inmate culture, and instructions on how to stay safe. Now they just have to convince the inmates and the officers that they are real inmates.
