My new obsession after Alone is now 60 Days In. It's an A&E show about people being plants within the jail system in the USA. The general purpose is these participants are supposed to last at least 2 months in a jail while reporting back problems within the system.
Every episode is available here:

Not a great platform for streaming, but if you want to watch and/or catch up for free it's the legal option.
