H is for Hawk follows Helen (Claire Foy), who, after the sudden death of her father (Brendan Gleeson), loses herself in the memories of their time birding and exploring the natural world together. She turns to the ancient art of falconry – rooted in European tradition – and trains a wild goshawk named Mabel as a way to navigate her profound loss. But as she teaches Mabel to hunt and fly free, Helen discovers how deeply she has neglected her own emotions and life. What begins as an act of endurance transforms into an intimate journey of resilience and healing.
