A mischievous Czech youngster sneaks off to the Lesna zoo for a day of fun. He soon bumps into (actually is bumped into by) a blind boy his own age (both about 11) whom he leads on a whirlwind tour of the premises, opening cages to allow his friend to pet everything from tiger cubs to rhinoceroses, always one step ahead of pursuing attendants. They eventually encounter some real perils but they are up to the challenge. Alas there is no English translation but the film is dubbed in German and even without language the story line is clear. Kids will enjoy it and parents will find it easy to watch. Sprinten wir! :-)
