De astronaut Brent reist zijn verdwenen collega's achterna en maakt een tijdssprong in de ruimte naar het jaar 3955. Hij landt op een door een atomaire ramp verwoeste aarde, waar vervaarlijke chimpansees het voor het zeggen hebben. Tweede deel van de Planet of the Apes-serie.
Nee, helaas is Beneath the Planet of the Apes nog niet beschikbaar op Netflix in Nederland.
