For sixth grader Marco, the minutiae of life revolve around taking the light rail with his best friend Chris and their Beyblade battles. But just like the Beyblades that spin in unpredictable directions, Chris is embarking on a different life path. Before Chris’s departure, they continue to linger around the neighbourhood playing with friends, uncertain about the future and how to say farewell. Tuen Mun, through the director’s lens, is slightly tinged with melancholy, resembling both a maze and a playground. In a child’s imaginative and innocent perspective, the film makes poignant observations on the anxieties of the adult world during the pandemic and how people deal with inevitable losses.
