Kam Muiday (Elaine JIN) has long been asking her granddaughter Sunnie Lam (CHUNG Suet Ying) to buy the same set of lucky numbers in each Mark Six lottery ticket for years. However, fate played a cruel trick. During the Lunar New Year’s "Snowball Draws", Sunnie was unable to place the bet, and that set of lucky numbers won a jackpot of HK$ 88.88 million.
