Den andra apfilmen tar vid där den första slutade. Den inleds med att
ytterligare två austronauter (Brent & "Skipper") landar på planeten efter att ha följt
samma bana som Taylor & Co gjort tidigare.
Brent möter - efter att ha begravt "Skipper" - Nova
och försöker få fram vad som har hänt Taylor.
Ultimately Brent and Nova stubmble upon vast underground passageways. This is
the dwelling of mutant humans who worship an atomic bomb and have
incredible power over other human minds. These mutants refuse to
fight or kill even in defense. But they do not hestitate to use
their powers to force others to do this for them. Taylor is captured
at this underground complex and forced to fight Brent. The mutant
that forces them to fight is ultimately killed by a spike in the jail
door. The Ape army is marching to this place beneath the city to
destroy it. An atom bomb is being prepared for a most dramatic display
or worship. As the missile slowly rises in the air the Apes try to
pull it down with ropes at first but without much luck. Taylor attempts
to stop the misile from firing and destroyong the world but an Ape
shoots him and he dies then so does the world.
