Once a famous and sought-after pop star, So Sing Wah has hit rock bottom. He cannot compose, he cannot sleep, and too often, he resorts to drinking. One day, a girl who claims to be the daughter of his high school love, Ha Man Huen, visits him, asking him to join her on a trip to Japan to spread Man Huen’s ashes and catch a rare sunrise – for the sake of the memory. Reluctantly, he agrees. Little does he know that this will be a journey in space and in time.
