This is the true story of Fu Manchu, an adult male orangutan, who
relishes outsmarting his friend, zookeeper Jerry Stones. He does just
that when he escapes his enclosure at will and spends sunny days with
the elephants in another part of the zoo. At first Jerry believes his
staff's carelessness allowed the crafty ape to get out. But when that
assumption proves wrong, he launches an all-out surveillance mission to
discover how Fu manages his getaways. Jerry soon discovers that Fu can
open the locked door, but can't figure out how he does it. The zookeeper
removes every twig and stick that could be used as a lock pick, but Fu
continues to escape. Eventually, Fu reveals to Jerry how he did it, and
is rewarded with honorary membership in the American Association of
Locksmiths.
