"Undo" is a poetic eco-documentary that explores the quiet conflict between tradition and sustainability. In many cultures, lighting plastic grave candles is a long-standing act of remembrance. But what remains after the ritual fades is a shell of waste - a “permanent flame” with a lasting ecological footprint. Combining authentic cemetery footage with personal reflections, "Undo" questions our habits, values, and responsibilities. An intimate reflection on memory, tradition, and the need for sustainable remembrance.
