Two urban exploration trips make up this episode of Epic Exploring. In Tallinn, Estonia, host Josh teams up with veteran urban explorer Steve Duncan to work through Patarei Prison, a former Soviet-era jail left to rot since the 1990s, its cell blocks and execution room still intact under peeling paint and rust. Meanwhile Cody heads to Vietnam with local guide Sherman Mak, traveling to Phan Thiet to track down the abandoned Suoi Cat amusement park, an overgrown theme park with rides frozen mid-decay in the jungle heat. The film cuts between the two locations and hosts, with each explorer narrating what they find room by room and ride by ride, reading the history of each site off the physical wreckage left behind: peeling propaganda murals in the prison, rusted carousel frames in the park. It is handheld, unscripted-feeling exploration footage rather than a formal historical documentary, built around curiosity about what gets left behind when a place empties out.
