The handover of Hong Kong from the United Kingdom to the People's Republic of China in 1997 caused an emigration of citizens to the West. We see the very moment when the girl Wai prepares to leave the city forever, but she leaves behind not only home, school, but also people.

This is the story of the meeting of Tokio and Wai. They talk to each other clumsily in a foreign language, getting frustrated when they can't express their thoughts. We were drawn into their conversation, because we also try to understand what they are saying. Their friendship is a bit odd and uncommon.
A character of particular importance is Grandma. The director gently tells us the fragile relationship between the girl and her grandmother.

One of the visual themes of the film is emptiness. The director has styled the image through an intriguing play of light and shadow, showing in an overexposed photo abandoned city, a concrete pier, a house drowning in darkness and loneliness in a hospital. We see Hong Kong through the lens of a Tokio camera, and in this image everything becomes blurred, white, and without the detail. Against this colourless backdrop, the emotions of the characters are more apparent.

The film is a great visual journey through the love that takes on different forms: first youthful love of Wai, mature love of Tokio full of boring routine, love between granddaughter and grandmother. If you want to watch something slow, a small story with a artistic picture of the Hong Kong with a bit of sad nostalgia – Autumn Moon is for you.
