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.

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?

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.

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.

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.

The midway point of the experiment approaches; anger rises among the women of F-Pod; an inmate in C-Pod poses a danger to one of the men.

Jeff is attacked by an inmate, putting the program at risk; Zac and Isaiah get moved to D-Pod; Barbara feels betrayed by her bunkies; Tami's wife makes a surprise visit; and Robert learns he's going back to general population.

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.

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.

The five remaining participants try to finish up their final days inside jail as pressure builds within the pods.

All seven participants meet to discuss their experience and tensions rise when a contentious moment is addressed.
