在动物王国里，如果你有抓不到的痒、吃不到的食物或者需要保证家庭的安全，你会怎么做？当然是找自己的搭档——但是这个搭档并不一定是同类。河马和鱼一起去角质。渡鸦邀请狼獾来吃晚餐，帮它们啃骨头。这个星球上的动物们通力协作，采用各种令人惊诧的方式合作，进行狩猎，修建巢穴等等，解决生存中的复杂问题，完成一些人类看似不可思议的目标。

In 1977, acclaimed director Barbet Schroeder and cinematographer Nestor Almendros entered the universe of the world’s most famous primate to create the captivating documentary Koko: A Talking Gorilla. The film introduces us to Koko soon after she was brought from the San Francisco Zoo to Stanford University by Dr. Penny Patterson for a controversial experiment—she would be taught the basics of human communication through American Sign Language. An entertaining, troubling, and still relevant documentary, Koko: A Talking Gorilla sheds light on the ongoing ethical and philosophical debates over the individual rights of animals and brings us face-to-face with an amazing gorilla caught in the middle.
