Sihja is a young, charming, and a little outrageous fairy, who leaves her forest home. In the city, she meets a sensitive new friend Alfred (11). Sihja loves the new-found organized urban shapes and orderly habits that humans have. The pair quickly bond and have a lot of fun, until one day dead birds appear on the city streets. The smelly fertilizer factory could be the culprit, but when Sihja reveals her uncontrolled fairy powers, people begin to be wary of her. Alfred and Sihja must find out what is threatening nature. With a clever and brave investigation, they manage to prevent an environmental disaster. Thanks to Alfred, Sihja learns to use her superpower and to apologise, while Alfred finds confidence to stand up for himself.
