In 60 Days In, participants are agreeing to be locked up in jail – with neither the guards nor prisoners knowing they haven't actually been convicted of a crime.
Two exclusive clips from the series show just how extreme things get when Zac, an ex-Marine and aspiring DEA agent who voluntarily was locked up, witnesses the beating of a prisoner named Ricky.
"The fight had an obvious cause and effect. Ricky was supposed to give his hash browns to Cody. He didn't give his hash browns to Cody. He got beat up for it. As long as I don't give anyone cause to fight me, there won't be that effect," says Zac.
Another clip shows Ricky instigating a fight with a man who exclaims that he didn't do anything.
The series is the brainchild of Sheriff Jamey Noel and Clark County Jail as a way to explore corruption in the jail system, which houses approximately 500 prisoners with crimes ranging from drug dealing to capital murder.
Although the series has yet to debut, PEOPLE can exclusively reveal that it has already been picked up for a second season
60 Days In premieres Thursday at 9 p.m. ET with back-to-back episodes on A&E. In subsequent weeks the show will air at 10 p.m. ET.
