Plunge tells the story of Katie who found empowerment, friendship, and healing by plunging into frigid waters of the sea. As her voice relates to us the physical and mental struggles that have plagued her for decades, her animated form darts confidently through kelp forests on the ocean floor. She tells us about her strong community and the tremendous physical benefits of cold-water swimming. Through Katie’s story this beautiful, animated film addresses themes of isolation and connection, mental health and wellbeing, and climate change and empowerment.
