Tian-Kuo (Eddie Peng) is a genial boy in his early twenties living with his parents, running deliveries for their small family-run restaurant, biking box lunches all over the city.

He often stops at the local swimming pool, dropping off orders for the team of deaf athletes who train there.

One day he notices Yang Yang (Ivy Chen), a young deaf girl who follows the team to cheer on her older sister Xiao Peng (Michelle Chen), who hopes to make the cut for the forthcoming Deaflympics.

However, when the time comes for the bill to be paid, Tian-Kuo pays instead so as to not hold up the line of waiting customers.

That same night, Xiao Peng, who has fallen asleep at home by herself, cannot hear the emergency services come when a fire breaks out in the apartment upstairs.

Xiao Peng drops out of the swimming competition, deciding to look for a job and practice on the side until she has regained her strength before competing again.
