A very funny movie about getting serious.
Biologist Alex Brisco develops a new method to communicate with chimpanzees. Instead of using machines, she teaches the chimps simple sign language. Her research is overlooked by ignorant colleagues, but one man, Mark, a cellist, helps Alex with her research.
