The film, produced by Anne Milne, Sonja Henrici, and Dewi Gregory, is a deeply personal exploration of the complex relationship between a young filmmaker and his father, an ICU doctor. At the heart of Night Gardener is a haunting story that has followed the director since childhood. As a boy, Daniel was deeply affected by his father's account of a man's suicide by stabbing himself in the heart. Years later, hoping to reconnect and capture this haunting tale, he visits his estranged father in a dilapidated cottage. The request to revisit the story abruptly ends their meeting — the last time they stayed together as father and son under the same roof before his father’s mental breakdown, institutionalisation, and death.
