Nine-year-old Lily Lo and her best friend Rosana are determined to win the big soccer match. But Lily's grandpa, Gung Gung, won't cheer or do "the wave" like the other parents and grandparents. Instead, he clips coupons in the bleachers.

Lily's frustration with the cultural divide leads to problems not just with her family, but with her friends and teammates, too. Strangely, an old family recipe for Wonton dumplings may just be the answer that brings luck and harmony to them all.
