Ape clothing matches that of 20th century Earth humans, except that the apes wear gloves instead of shoes on their prehensile feet. Ulysse is captured with the survivors and brought to a city populated by apes. Gorillas, fully dressed as hunters, attack the tribe with firearms. Her tribe, who exhibit the behavior of dumb animals, wreck the newcomers' clothing and shuttle. She is frightened by their pet chimpanzee, Hector, and strangles it.

Attracted by a woman whom they call Nova, they swim below a scenic waterfall. They can breathe the air, drink the water and eat the fruit. They land their shuttle on a temperate, lushly forested planet which they name Soror ( Latin for sister). Because they travel close to the speed of light, time dilation causes centuries to pass on Earth during their two years in transit. The manuscript was written by journalist Ulysse Mérou, who in 2500 was invited by wealthy Professor Antelle to accompany him and his disciple, physician Arthur Levain, to Betelgeuse. In a frame story, a rich couple sailing alone in space, Jinn and Phyllis, rescue and translate a manuscript from a floating bottle.

The novel tells the tale of three human explorers from Earth who visit a planet orbiting the star Betelgeuse, in which great apes are the dominant intelligent and civilized species, whereas humans are reduced to a savage animal-like state. It was adapted into the 1968 film Planet of the Apes, launching the Planet of the Apes media franchise. La Planète des singes, known in English as Planet of the Apes in the US and Monkey Planet in the UK, is a 1963 science fiction novel by French author Pierre Boulle.
