We are the Littles.

Several young men who love volleyball suffer discrimination because their height isn't up to the standard. They come across Chang Ka Yu, a former member of the Hong Kong women's volleyball team who volleyball dream was shattered. They fire up Ka Yu's volleyball spirit with youth and passion, making her the first female coach in the history of Hong Kong men's volleyball. Together, they prove themselves through their actions and send out a message, "We are the Littles, but don't underestimate us!"
