A little piglet named Foontic ran away from his owner, Mrs. Belladonna, because he didn't want to deceive children. Mrs. Belladonna is determined to find him.

About how the evil and greedy owner of the department store "Tears of a Child" Mrs. Belladonna tried to steal away escaped Foontic from the clown Fokus-Mokus.

Dressed in a men's costume, Belladonna tries to kidnap Foontic. She is assisted by the dim-witted police chief Foxtrot and the fussy detectives Dober and Pincher.

Foontic and his new friends once again outwit the evil Mrs. Belladonna, who, under the influence of sleeping pills, is taken in the middle of the night in their car to the Three Roads roadside hotel and handed over to her old friend, an equally greedy and cynical businessman named Durillo. When she regains consciousness, Belladonna resumes her pursuit of Foontic, who, together with the kind-hearted clown Mokus, the clever monkey Bambino, and the hippopotamus Chocolate, is preparing to put on a grand circus show in the city.
