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. Tian-Kuo is instantly smitten with Yang Yang. With the use of sign language, he tries to strike up a friendship with her, hoping it will lead to something more.
