Kuen is a lounge singer on Temple Street. Her son Kakei, now a university student, returns to Hong Kong for just a few days after emigrating to Canada with his father. Kuen's colleague Kit has to work overnight and enlists Kuen’s help to take care of her young son. During the sleepless night, Kuen and Ka-kei relive their past and envisage their future through another pair of mother and son. Under the bright sun, the cycle of life and family relationships continue, made all the more touching by the nuanced moments of care and concern between each other. SHAM Ka-ki of Weeds On Fire plays the son and renders a tender and layered performance full of subtlety.
