A young boy and his sister spend a summer at their grandparents’ house in the country while their mother recovers from an illness. The children spend most of their time climbing trees and swimming, but as the summer progresses they slowly begin to come to terms with the enigmatic and occasionally threatening realities of adult life. A Summer at Grandpa’s is a contemplative and profoundly moving coming-of-age tale that is entrancingly attuned to the minutiae of daily life and the clash of innocence and experience.
