Author and wildlife rehabber Terry Masear has an ambitious goal: to save every injured hummingbird in Los Angeles. But the path to survival is fraught with danger. This heart-expanding Sundance hit introduces audiences to Terry's diminutive patients through breathtaking slow-motion photography and emotional storytelling. Over the course of director Sally Aitken's moving documentary, we become deeply invested in baby hummingbirds like Cactus and Wasabi, celebrating their tiny victories and lamenting their tragedies. Through Terry's eyes, each bird becomes memorable, mighty and heroic. Her compassion and empathy serves as a reminder that grace can be found in the smallest of acts and the tiniest of creatures.
