Dr Jane Goodall and her team rescue and help chimpanzees in danger and elaborate on the beautiful bond that one can create with animals, providing a remarkable window into humankind's closest living relatives.

Rebeca returns from a rescue mission in Angola with eight chimpanzees; scientists study the survival skills of the group, which they release into the wild; researchers also develop a mandrill reintroduction program.

The release group's survival tests continue, and we meet the other animals cared for at Tchimpounga.

Recent arrival Aymard meets his surrogate mom and a very sick infant chimpanzee, John, is rescued and brought to Tchimpounga by plane; Rebeca spends time with her chimpanzee family.

Jane Goodall braves a realm of unknowns to give the world a remarkable window into humankind's closest living relatives.
