Grandpa (Koo Chuen) and Grandma (Mei Fong) live in the fertile Taiwanese countryside. A boy (Wang Chi-Kwang) and his sister (Sun Cheeng-Lee) are packed off to their grandparents when their mother falls ill. Though relationships are strained at first, the boy and girl end up having a wonderful summer with grandpa, as the old man takes them on fishing trips and helps them in their search for a lost cow. Summer At Grandpa's didn't have a very long theatrical life in Taiwan, though it proved more successful on the international scene. The film's original title was Tung-Tung-Te-Chia-Ch'i, which in itself is reason enough to see it.~ Hal Erickson, All Movie Guide
