The old willow tree has stood in the schoolyard for as long as anyone can remember. It's a gathering place, a run-laps-around place, a dream-under place. Until one blustery night when a storm blows it over.

Brokenhearted over the loss of their beloved tree, the students come up with a wonderfully wild idea: to grow new willows! With nature as their classroom, they immerse themselves in the sensory experience of the outdoors as they gather branches and trim clippings. Before long, many new trees begin to take root. But their wonderfully wild ideas don't stop there. Can the class encourage their community to reconnect with nature and transform their entire schoolyard?
