Ben Fogle heads to Slab City in the Sonora desert, California to explore a unique, off grid, alternative lifestyle community who live in the 'last free place in America'. An enigma, with a lawless reputation, Slab City takes its name from concrete slabs that remained after World War ll Marine training camp was torn down. Part artists' colony, part homeless city, this one-square-mile patch of desert is divided into unique neighbourhoods with different characteristics - from Pirate Camp to East Jesus Art collective and the LGBTQIA, Flamingo Camp.
