Six months after the Season 4 program at the Fulton County Jail, we catch up with the most controversial group of participants 60 Days In has ever known.

Six months after the completion of Phase One of Colonel Mark Adger's unprecedented program at the Fulton County Jail, the seven participants return to their everyday lives with new perspectives gained from their time behind bars.

After the most shocking finale in the program's history, all nine participants sit down with Journalist Soledad O'Brien and Colonel Mark Adger to discuss their experiences at the Fulton County Jail.

Colonel Adger must work against the clock to safely remove all the participants from the Fulton County Jail.

A participant is removed from the program after it is learned that they intentionally broke their cover with an inmate. Stephanie fears that Gabrielle will not keep Angele's secret, and Alan tries to buy meth.

After an emotional breakdown, one participant is not sure he can continue in the program; Nate expands his meth investigation.

Matt wrestles with the most devastating moment of his life, Alan gets a mysterious new cellmate, and the inmates throw an unforgettable birthday party.

Two participants struggle with the decision to leave the program early, while the rest try to keep their wits as they finish the back half of their time in the Fulton County Jail.

When Jaclin tries to help Stephanie switch rooms, it puts a target on Jaclin's back, Emmanuel also becomes a target when he tries to break up a fight, and a rumor about Andrew being gay could put him in harm's way.

The participants are faced with challenges when a gas scare happens in the women's pod, a football kitty goes missing in 500 prompting a gang fight, and a new inmate in 600 tests Matt.

While Stephanie chooses to use drugs to bond with her fellow inmates, Jaclin finds acceptance by creating her own jail clothing line, bringing pink flare and positivity to the inmates of I-Pod, but causing heated confrontations with the officers.

The participants toe the line between blowing their cover or going full inmate while trying to stay focused on their purpose in the midst of wild parties and difficult cellmates.

In I-Pod, Jaclin begins to alienate the officers, inmates and her fellow participant, Stephanie, who decides to plot against her. Meanwhile, Zone 500 is raided for contraband after Alan's roommate makes a shank, and Matt is at odds with his roommate Lawrencein Zone 600, and fears he may have to fight him.

As the phase two participants settle into the Fulton County Jail and new ones enter, inmate feuds and power-plays bring participants face to face with real danger and real charges.

With two participants already inside the jail and three more entering, phase two will shatter expectations, open old wounds, and put everyone's safety in jeopardy.
