War for the Planet of the Apes starts with a war. But before that, the movie opens with multiple paragraphs on the screen which you have to read quickly to get the context.
Humans are afflicted by a deadly virus which makes them lose their power of speech and at the same time, the apes are getting more intelligent and acquiring power of speech. Hence the army of Humans want to eradicate the apes before the table turns.
