Chimpanzees do tricks for the spectators at an American zoo.
Titles read: "Walks and Walkers".
United States of America.
Various shots of chimpanzees in a cage at the zoo. Their keeper involves them in a kind of show for the spectators. The four chimps walk across the cage in formation, then perform several tricks, such as walking along on a rolling ball and riding little tricycles. One chimp hammers the wheel of a tricycle.
This isn't very nice, unless you like animals in cages doing tricks for crowds of guffawing humans.
