Hoppers

In the city of Beaverton, Mabel Tanaka spends her childhood with her grandmother in a nearby forest glade inhabited by many wild animals, particularly a colony of beavers. Inspired by her grandmother, Mabel grows up with a deep appreciation for nature and continues watching over the glade after her grandmother's death. When Beaverton's mayor, Jerry Generazzo, announces plans to replace the glade with a freeway, Mabel campaigns against the project but receives no support. Her activism causes her to neglect her college studies, to the disapproval of her biology professor, Dr. Samantha "Sam" Fairfax.
