Mabel

Biracial Callie (Lexi Perkel) loves trees and plants and little else in Nicholas Ma's warm debut feature. Surly with her parents and intolerant of people who don't share her interest, she's also unhappy about changing schools after her family relocates. But as luck would have it, substitute teacher Ms. G (Judy Greer) is starting a botany unit in science class, and Callie wangles her way in. Held rapt by Ms. G's lectures and online speeches, Callie develops an experiment raising chrysanthemums in darkness and manages to lure Agnes, her ebullient younger neighbor, into working on the project with her. Precocious, determined, and wryly funny, Callie is a unique protagonist who leverages her love of botany to propel herself into adolescence.
