When a group of trespassing seniors swim in a pool containing alien cocoons, they find themselves energized with youthful vigor.

The sole survivor of an interplanetary rescue mission discovers a planet ruled by apes, and an underground city run by telepathic humans.

When an in-flight collision incapacitates the pilots of an airplane bound for Los Angeles, stewardess Nancy Pryor is forced to take over the controls. From the ground, her boyfriend Alan Murdock, a retired test pilot, tries to talk her through piloting and landing the 747 aircraft. Worse yet, the anxious passengers — among which are a noisy nun and a cranky man — are aggravating the already tense atmosphere.

Astronaut Taylor crash lands on a distant planet ruled by apes who use a primitive race of humans for experimentation and sport. Soon Taylor finds himself among the hunted, his life in the hands of a benevolent chimpanzee scientist.
