An anarchists’ retreat in Mexico (much to the chagrin of the locals) turns a pleasure paradise into a danger zone in the new trailer for HBO’s “The Anarchists.”The trailer hypes up the doc’s focus on the anarchist lifestyle, including their typical beliefs and way of life, their meetups and their penchant for investing in crypto. But things go awry when a murder happens among them.Across the series, “The Anarchists” “follows individuals engaged in this movement with full access to the drama that ensues as a community tries to live alongside tourists and drug cartels with only the principles of anarchy as their guideposts,” per a logline from the network.
