Years after the events depicted in Rise of the Planet of the Apes, Caesar and the liberated apes have developed a forested
encampment outside of San Francisco; the so - called «Simian Flu» unleashed by Franco's well - intentioned Alzheimer's researcher has scrubbed out much of humanity, and shattered the country's infrastructure.
The refugees suffer from a host of issues associated with long - term
encampment, such as overcrowding, delinquency, physical abuse, alcoholism and depression as well as the threat of harassment and deportation by Thai authorities should refugees venture
outside the camps seeking employment.
