Late 21st century. Archeologists unearthed a company of century-old military robots, but lost them during the transportation.

Now those two have to stop the robots before much damage has been done.

They are neither adults nor kids - somewhere in between, living in their separate boys and girls cozy dorms and doing whatever they love to do - inventors, artists, poets, mechanists, scientists and....just dreamers! These enthusiastic and creative folks enjoy their half-adult, half-childish lifestyles and entertain each other with the different tricks and practical jokes. The main hero stands out of the crowd - while the others try to live the normal life socializing as they can, he can never be rested, always coming up with the different unpredictable and unexpected moves, which always make viewers burst with laugh....

To Moscow have arrived the participants of the international conference of the zoophilologists and also the international jury which is to elect for the world festival the best performance of the program of Moscow circus. Mrs Whistler (Iva Janzurová), British associate professor, makes her understood with the animals in their language but the Czech professor Ruzicka (Jirí Sovák), though he is capable of using the animals language, prefers teaching the animals the human language. Ruzicka's friend, the poodle Archibald, speaks "in Human" very well. The scientific dispute ends with a bet - if Ruzicka teaches the circus elephant to sing, Mrs Whistler will eat up her hat.
