"Lingering Echoes of Time" follows the journey of a delayed message, questioning if its significance endures through time. It plays around with multiple realities like the present, the imagination, and the memory and what could-have-been. It uses different visual styles and techniques like motion design, frame-by-frame animation, and 3D animation to represent reality and imagination. It explores the passage of time using natural elements like changing colors of the butterfly, daytime and nighttime, water and ice, flowers and rain. The film is a meditation, where the audience can reflect on their relationship with the past, present and the future.
