Terry Masear wants to save every injured hummingbird in Los Angeles, but the path to survival is fraught with uncertainty and drama. This intimate and profound story of rescuing the fastest things on wings leans in deep to reveal the hummingbird as it’s never been seen before, both visually but also in terms of its personality. Through the eyes of America’s busiest bird rehabilitator, each bird becomes memorable, mighty and heroic. Terry knows their secrets. As marvels of natural engineering and, for Terry, messengers from the other side, the film challenges us to ask: when we choose to save another, can we find a blueprint to save ourselves?
