A young witch named Kiki and her chatty black cat Jiji befriend a bakery owner. Kiki is an enterprising young girl, but she must follow tradition in order to become a full-fledged witch. Landing in a far-off city, and with the help of her new friend, she sets up a high-flying delivery service and begins a wonderful experience of independence and responsibility as she finds her place in the world.

A black kitten who is shunned by the other cats because they think he is bad luck meets a white butterfly who leads him through the city--where he goes from one mishap to another--before telling him a secret.
