It is the year 2029: Astronaut Leo Davidson (Mark Wahlberg) boards a pod cruiser on a Space Station for a "routine" reconnaissance mission. But an aburupt detour through a space time wormhole lands him on a strange planet where talking apes rule over the human race. With the help of a sympathetic chimpanzee activist named Ari (Helena Bonham-Carter) and a small band of human rebels, Leo leads the effort to evade the advancing Gorilla Army led by General Thade (Tim Roth) and his most trusted warrior Attar (Michael Clarke Duncan). Now the race is on to reach a sacred temple within the planet's Forbidden Zone to discover the shocking secrets of mankind's past - and the key to it's future.
