Sheriff Mike Smith prepares seven volunteers to go inside the Utah County Jail to reveal all the problems that have been out of sight-until now.

The first three participants enter Utah County Jail to begin their 60 days undercover.

Scarlett, Daniel, and Corey try to find their way in the Utah County Jail. Daniel makes mistakes that could put him in danger. Scarlett is troubled by a bossy trustee. Corey's sexuality becomes a source of conflict but a new cellmate offers acceptance.

Three more participants enter general population as Corey's dental distress sends him over the edge.

The team struggles to adapt to life inside. As the final participant enters the jail, the pact is already broken.

The desolate reality of jail continues to challenge the team, causing a second participant to give the emergency signal.

As the team continues its time in jail, some participants navigate their new surroundings while another finds it too much to handle.

Conflicts with inmates and growing suspicion spells trouble for the team, and one participant is moved out of the pod.

As a new participant enters the jail, the rest of the team is at their breaking point, which leads to a dangerous discovery.

The Sheriff's team takes unprecedented measures to protect Daniel when his true identity is discovered. An incident in the women's pod causes Nina and Scarlett to sever their bond as teammates.

With the end of the program drawing near, the participants struggle to tie up loose ends, fend off suspicion, and face real problems in the jail.

After the remaining participants are released, they meet with Sheriff Smith and his team to discuss their time inside the Utah County Jail and find out which team members finished the program.

Now that all the participants have left, they sit down with the Sheriff and his team to reflect on necessary changes they hope will be made at the Utah County Jail.
