Remember the back-to-the-land movement of the mid-1960s, which lasted well into the late 1970s? It was a counterculture response to urban living with its many problems – traffic, pollution, crime, political turmoil, etc.. Young people, in particular, were looking for healthier, more sustainable lifestyles such as growing their own food and living off the land. Although this cultural phenomenon mostly occurred in North America, the idea was co-opted by young idealists around the world, even in such far away places as Tingo Maria, Peru. That is the setting of the 1969 film La Muralla Verde (English title, The Green Wall), the story of Mario (Julio Aleman), a recently married businessman, who becomes fed up with city living in Lima and convinces his wife Delba (Sandra Riva) to start a new life on the land he has purchased in the Peruvian jungle. Along with their newborn son Romulo, the couple set off on a new chapter in their lives with high hopes.
